The twin issues we shall decide in this case are whether Maryland recognizes the mitigation defense of “imperfect self defense” and, if so, whether that defense applies to the statutory offense of assault with intent to murder under Maryland Code (1957, 1982 Repl.Vol.), Art. 27, § 12.
We set forth a shortened version of the facts that give rise to these issues. On September 15, 1981, the Emanuel brothers, Jimmy and Rickey, became embroiled in an argument with Melvin J. Faulkner, Jr. outside of a Baltimore City bar. This argument quickly escalated into a fight between Jimmy and Faulkner. Because Faulkner believed that Jimmy was armed with a knife, Faulkner produced a handgun and began firing. Faulkner, however, shot Rickey twice in the chest as Rickey tried to push his brother from the handgun’s line of fire. The testimony reflects considerable conflict as to what led Faulkner to believe that Jimmy was armed with a knife, which participant was the aggressor at various stages of this imbroglio, who entered into the melee mutually and willfully, and who was simply acting in self defense.
*485 Faulkner was charged with assault with intent to murder and related offenses. At his trial in the Criminal Court of Baltimore (now Circuit Court for Baltimore City), the court instructed the jury as to the defenses of justification by way of self defense and mitigation by way of hot-blooded response to the provocation of mutual combat. The court, however, declined Faulkner’s request that the jury also be instructed as to the defense of “imperfect self defense.” The jury subsequently found Faulkner guilty of assault with intent to murder and related handgun offenses. In a divided decision, the Court of Special Appeals reversed, holding that the trial court erred in refusing to instruct the jury as to the defense of imperfect self defense. Faulkner v. State, 54 Md.App. 113, 458 A.2d 81 (1983). We granted the State’s petition for a writ of certiorari to address the important issues presented.
I
Initially, we note that the difference between murder and manslaughter is the presence or absence of malice. State v. Ward, 284 Md. 189, 195, 396 A.2d 1041 (1978); Davis v. State, 39 Md. 355 (1874); Weighorst v. State, 7 Md. 442 (1855). Self defense operates as a complete defense to either murder or manslaughter. A successful self defense, therefore, results in the acquittal of the defendant. We have summarized the elements necessary to justify a homicide, other than felony murder, on the basis of self defense in the following terms:
(1) The accused must have had reasonable grounds to believe himself in apparent imminent or immediate danger of death or serious bodily harm from his assailant or potential assailant;
(2) The accused must have in fact believed himself in this danger;
(3) The accused claiming the right of self defense must not have been the aggressor or provoked the conflict; and
*486 (4) The force used must have not been unreasonable and excessive, that is, the force must not have been more force than the exigency demanded.
See Tichnell v. State, 287 Md. 695, 718, 415 A.2d 830 (1980) (Tichnell I) (quoting Guerriero v. State, 213 Md. 545, 549, 132 A.2d 466 (1957)); DeVaughn v. State, 232 Md. 447, 453, 194 A.2d 109 (1963), cert. denied, 376 U.S. 927, 84 S.Ct. 693, 11 L.Ed.2d 623 (1964); Bruce v. State, 218 Md. 87, 96-97, 145 A.2d 428 (1958) (discussing elements of self defense in a review of jury instructions given on the subject).
Imperfect self defense, by contrast, is not a complete defense. Its chief characteristic is that it operates to negate malice, an element the State must prove to establish murder. As a result, the successful invocation of this doctrine does not completely exonerate the defendant, but mitigates murder to voluntary manslaughter.
There are other types of defenses that mitigate murder to manslaughter but do not fall under the umbrella of imperfect self defense. Commonly regarded as falling within this group are killings stemming from a heat of passion, such as (1) discovering a spouse in the act of sexual intercourse with another; (2) mutual combat; and (3) assault and battery. See Tripp v. State, 36 Md.App. 459, 374 A.2d 384 (1977); Bartram v. State, 33 Md.App. 115, 364 A.2d 1119 (1976); Whitehead v. State, 9 Md.App. 7, 262 A.2d 316 (1970). These acts, because they create passion in the defendant and are not the product of a free will, negate malice and thus mitigate a homicide to manslaughter.
Imperfect self defense, however, is different from either self defense or the commonly recognized mitigation defenses. Because the doctrine of imperfect self defense has been subjected to different interpretations and regarded by some courts and scholars as being a recent theory not far advanced, we believe a brief examination of its history and development will help clarify its nature and scope and point out the differences.
*487 The rudimentary principles of imperfect self defense appeared in a series of manslaughter statutes enacted in England between 1496 and 1547. See R. Moreland, The Law of Homicide 91 (1952). According to Professor More-land, these statutes reflected a compromise between murder and complete exoneration in those instances where a defendant’s conduct warranted neither a murder conviction nor an acquittal. Out of these statutes arose the mitigating defense of imperfect self defense, which was predicated upon a “fear of life.” Imperfect self defense was applicable to a crime without passion so as to distinguish it from the mitigation defense founded upon heat of passion. However, because the defendant was at fault the law demanded that he bear some criminal responsibility for the homicide although he lacked the requisite mens rea for murder. Professor Moreland put it this way:
In each case [homicide arising from provocation (crime of passion) and one arising from a “fear of life” (crime without passion)] the accused might well be held for murder or he might be excused because of the circumstances for committing the crime; but the law compromises, takes a middle ground, and holds him guilty of manslaughter. Thus, in the case of imperfect self defense, the law might refuse him the opportunity to plead self-defense because of his fault and hold him guilty of murder, or it might waive his fault and allow him to utilize the excuse of self-defense. Balancing the two, the law strikes a middle ground as a matter of policy and rather reasonably convicts him of voluntary manslaughter.
In concert with the above, Professor Perkins recognized that manslaughter is a “catch-all” concept that encompasses a variety of homicides that are “neither murder nor innocent.” R. Perkins, Criminal Law 69 (2d ed. 1969). In elaborating upon this proposition, Professor Perkins explained:
Since manslaughter is a “catch-all” concept, covering all homicides which are neither murder nor innocent, it *488 logically includes some killings involving other types of mitigation, and such is the rule of the common law. For example, if one man kills another intentionally, under circumstances beyond the scope of innocent homicide, the facts may come so close to justification or excuse that the killing will be classed as voluntary manslaughter rather than murder. “It is not always necessary to show that the killing was done in the heat of passion, to reduce the crime to manslaughter;” said the Arkansas court, “for, where the killing was done because the slayer believes that he is in great danger, but the facts do not warrant such a belief, it may be murder or manslaughter according to the circumstances, even though there be no passion.” To give another illustration, the intentional taking of human life to prevent crime may fall a little short of complete justification or excuse and still be without malice aforethought.

The doctrine of imperfect self defense gained a foothold in the United States in the late 1800’s. The “cornerstone” case for this defense is an 1882 decision by the Court of Criminal Appeals of Texas. Reed v. State, 11 Tex.Crim. App. 509 (1882). In discussing the doctrine the Reed court remarked:
It [self defense] may be divided into two general classes, to wit, perfect and imperfect right of self defense____ If, however, [the defendant] was in the wrong, — if he was himself violating or in the act of violating the law, — and on account of his own wrong was placed in a situation wherein it became necessary for him to defend himself against an attack made upon himself which was superinduced or created by his own wrong, then the law justly limits his right of self defense, and regulates it according to the magnitude of his own wrong. Such a state of case may be said to illustrate and determine what in law would be denominated the imperfect right of self-defense. Whenever a party by his own wrongful act produces a condition of things wherein it becomes necessary for his *489 own safety that he should take life or do serious bodily harm, then indeed the law wisely imputes to him his own wrong and its consequences to the extent that they may and should be considered in determining the grade of offense which but for such acts would never have been occasioned.
Id. at 517-18. Shortly after Reed, courts fashioned three variations of the doctrine.
First, some courts indicated that the doctrine would apply where the homicide would fall within the perfect self defense doctrine but for the fault of the defendant in provoking or initiating the difficulty at the non-deadly force level. E.g., Allison v. State, 74 Ark. 444, 86 S.W. 409 (1905) (dictum); Reed v. State, supra; State v. Flory, 40 Wyo. 184, 276 P. 458 (1929) (dictum). Second, courts noted that the doctrine would apply when the defendant committed a homicide because of a honest but unreasonable belief that he was about to suffer death or serious bodily harm. E.g., Allison v. State, supra (dictum); State v. Thomas, 184 N.C. 757, 114 S.E. 834 (1922). Third, other courts recognized the doctrine when the defendant used unreasonable force in defending himself and, as a result, killed his opponent. See, e.g., State v. Clark, 69 Kan. 576, 77 P. 287 (1904).
Since the acceptance of this doctrine by several jurisdictions during the late 1800’s and early 1900’s, comparatively few modern jurisdictions have analyzed the doctrine. Of those jurisdictions that have considered the doctrine in recent times, however, several have adopted the honest but unreasonable belief variation of the imperfect self defense doctrine. For example, in providing a comprehensive discussion of the honest but unreasonable belief standard, the Supreme Court of California in People v. Flannel, 25 Cal.3d 668, 603 P.2d 1, 160 Cal.Rptr. 84 (1979), sought to eliminate the “obfuscat[ion] by infrequent reference and inadequate elucidation” of what it characterized as a unique rule. Id. 25 Cal.3d at 681, 603 P.2d at 8, 160 Cal.Rptr. at 91. Consistent with Professor Moreland’s view, the Flannel court observed that the unreasonable belief theory of imperfect *490 self defense is not limited by or bound up with the concept of the mitigating defense of heat of passion.
In addition, the court explained that the reasonableness of an individual’s honest belief that he needs to repel imminent peril or bodily injury simply goes to the justification for the homicide. Moreover, the Flannel court emphasized the weighing of competing interests in determining the applicability of this mitigation defense. In writing for the court, Justice Tobriner observed:
[T]he state has no legitimate interest in obtaining a conviction of murder when, by virtue of defendant’s unreasonable belief, the jury entertains a reasonable doubt whether defendant harbored malice. Likewise, a defendant has no legitimate interest in complete exculpation when acting outside the range of reasonable behavior. The vice is the element of malice; in its absence the level of guilt must decline.
Id. Id. 25 Cal.3d at 680, 603 P.2d at 7, 160 Cal.Rptr. at 90 (citations omitted). This reasoning is persuasive because it recognizes that a defendant’s culpability for a homicide be mitigated when he lacks the requisite mens rea for the offense of murder. Jurisdictions in addition to California have likewise recognized the honest but unreasonable belief standard on the basis of decisional law. Hartfield v. State, 176 Miss. 776, 170 So. 531 (1936); Wood v. State, 486 P.2d 750 (Okla.Crim.App.1971).
Unlike California and several other jurisdictions, some states apparently do not recognize the honest but unreasonable belief standard of imperfect self defense. For instance, in a 1944 decision, the Supreme Court of Missouri suggested in dictum that a person may avail himself of the doctrine of imperfect self defense when he is the initial aggressor or when he voluntarily enters a difficulty without a felonious intent and is forced to commit a homicide to save his life. State v. Ferguson, 353 Mo. 46, 182 S.W.2d 38 (1944); see State v. Mayberry, 360 Mo. 35, 226 S.W.2d 725 (1950) (defendant entitled to voluntary manslaughter instruction when evidence shows that he lacked malice in *491 committing the homicide); State v. Phroper, 619 S.W.2d 83 (Mo.Ct.App.1981) (dictum) (aggressor may use imperfect self defense provided he enters an encounter without felonious intent).
North Carolina has carefully articulated a formula-based standard for determining whether a defendant charged with murder is entitled to an instruction on the doctrine of imperfect self defense. This standard, unique in its clarity, uses the elements of perfect self defense as its benchmark. Under this approach, perfect self defense excuses a homicide when it is shown that, at the time of the homicide, the:
(1) Defendant subjectively believed it necessary to kill the deceased to save himself from death or great bodily harm;
(2) Defendant’s belief was objectively reasonable;
(3) Defendant was not the aggressor in bringing on the affray, i.e., he did not aggressively and willingly enter into the fight without legal excuse or provocation; and
(4) Defendant did not use excessive force.
Imperfect self defense, by contrast, arises when only elements (1) and (2) above are present. State v. Bush, 307 N.C. 152, 297 S.E.2d 563, 568 (1982). The Bush court elaborated upon its standard in the following terms:
[I]f the defendant believed it was necessary to kill the deceased in order to save himself from death or great bodily harm, and the defendant’s belief was reasonable because the circumstances at the time were sufficient to create such a belief in the mind of a person of ordinary firmness, but the defendant, although without murderous intent, was the aggressor or used excessive force, the defendant would have lost the benefit of perfect self defense. In this situation he would have shown only that he exercised the imperfect right of self-defense and would remain guilty of at least voluntary manslaughter. However, both elements (1) and (2) [above] must be shown to exist before the defendant will be entitled to the benefit of either perfect or imperfect self defense.
*492 Id. (citation omitted); State v. Marlow, 310 N.C. 507, 313 S.E.2d 532 (1984); State v. Wallace, 309 N.C. 141, 305 S.E.2d 548 (1983). See generally Casenote, Criminal Law — Perfecting the Imperfect Right of Self Defense— State v. Norris, 303 N.C. 526, 279 S.E.2d 570 (1981), 4 Campbell L.Rev. 427 (1982) (discussing North Carolina’s version of imperfect self defense). This particular formulation, which evidently has not been adopted by other jurisdictions, does not embrace the honest but unreasonable belief standard because a defendant must both objectively and subjectively believe that he must resort to deadly force to prevent death or serious bodily harm. Only if the defendant satisfies these two criteria may he invoke the imperfect self defense doctrine if he was the initial aggressor or used excessive force in defending himself. In sum, although several jurisdictions have adopted the doctrine by means of case law, they are not in agreement as to the standard that should be applied. 1
Many states that recognize the doctrine on the basis of statutory law have adopted the subjectively honest but objectively unreasonable standard of the imperfect self defense doctrine. Ill.Ann.Stat. ch. 38, § 9-2 (Smith-Hurd Supp. 1984-1985); 18 Pa.Cons.Stat.Ann. § 2503(b) (Purdon 1983); Tex.Penal Code Ann. § 9.32 (Vernon Supp.1984); Wis.Stat.Ann. § 940.05(2) (West 1982). For example, Pennsylvania, which has “long recognized” this mitigation defense, Commonwealth v. Cain, 484 Pa. 240, 398 A.2d 1359, 1361 (1979); see Commonwealth v. Nau, 473 Pa. 1, 373 A.2d 449, 452 n. 5 (1977) (citing cases), has a statute governing voluntary manslaughter that embodies the doc *493 trine of imperfect self defense. See 18 Pa.Cons.Stat.Ann. § 2503(b) (Purdon 1983). This statute provides:
(b) Unreasonable belief killing justifiable. — A person who intentionally or knowingly kills an individual commits voluntary manslaughter if at the time of the killing he believes the circumstances to be such that, if they existed, would justify the killing under Chapter 5 of this title (relating to general principles of justification), but his belief is unreasonable.
Id. (emphasis supplied). In a recent interpretation of this statute, the Supreme Court of Pennsylvania noted that homicide is mitigated from murder to voluntary manslaughter when the defendant subjectively believes circumstances exist to justify the killing, but objective reality negates that existence. Commonwealth v. Carter, 502 Pa. 433, 466 A.2d 1328, 1332 (1983). “Logically, the defendant’s belief, sincere though unreasonable, negates malice.” Id. This statute thus permits mitigation under the theory of mistaken belief of the existence of facts that would have justified the killing had those facts actually existed.
Similar to Pennsylvania, Illinois 2 and Wisconsin 3 have likewise codified the imperfect self defense doctrine in their *494 voluntary manslaughter statutes based upon the honest but unreasonable belief standard. Wisconsin’s statute, however, differs in wording from the Pennsylvania and Illinois laws. Under the the Wisconsin statute a defendant commits voluntary manslaughter on the basis of imperfect self defense when he believes that the act causing the death was necessary in the exercise of self defense but that the belief was unreasonable under the circumstances, State v. Kelley, 107 Wis.2d 540, 319 N.W.2d 869, 873 (1982); Roe v. State, 95 Wis.2d 226, 290 N.W.2d 291, 300 (1980), or he believes that the necessity of self defense is reasonable, but the deadly force used was unnecessary. Ross v. State, 61 Wis.2d 160, 211 N.W.2d 827, 830 (1973). Wisconsin’s law thus goes a step further than the Pennsylvania and Illinois statutes by permitting a defendant to assert imperfect self defense when he resorts to unnecessary force although he reasonably believes that he must engage in self defense. Further, Ross apparently indicates that a defense predicated upon the unnecessary force variation of the doctrine cannot coexist with the honest but unreasonable belief variation. In short, a defendant relying upon the unnecessary force variation must have reasonably believed that he had to defend himself. The reverse is apparently also true: a defendant who honestly but unreasonably believed that he had to resort to self defense cannot use unnecessary force.
The Texas statute 4 governing imperfect self defense is “intricate” and is based upon the rationale that “a person *495 may not take advantage of a necessity he has brought upon himself.” Texas Penal Code Ann. § 9.32 practice commentary at 347 (Vernon 1974). Section 9.32 provides that when a person provokes a difficulty and then threatens or uses deadly force, the trier of fact is required to weigh the respective fault of the parties. The trier of fact focuses upon the culpable mental state required for the offense allegedly committed by the defendant. For instance, if a person provokes a difficulty without an intent to kill his opponent, but the victim reacts with the excessive use of deadly force, the person may be guilty of voluntary manslaughter depending on his culpability in the encounter. Id. at 348 (discussing situations where imperfect self defense would apply); see Semaire v. State, 612 S.W.2d 528 (Tex.Crim.App. 1980).
In light of those decisions adopting the doctrine and the statutes providing for this mitigation defense, it is necessary to review Maryland’s relatively recent venture into this area. Although other jurisdictions have long debated the merits of the doctrine, Maryland’s experience with this doctrine is scarcely a decade old. Since 1975, the Court of Special Appeals has discussed the doctrine on at least six occasions, with four of the cases decided in 1975. Beginning with Evans v. State, 28 Md.App. 640, 658 n. 4, 349 A.2d 300 (1975), aff'd, 278 Md. 197, 362 A.2d 629 (1976), the Court of Special Appeals observed that the doctrine was “little more than an academic possibility”. As discussed more fully below, this premature observation was dispelled later that year in Shuck v. State, 29 Md.App. 33, 349 A.2d 378 (1975), cert. denied, 278 Md. 733 (1976).
Shuck originated as a friendly automobile race between a Corvette sports car occupied by Jackman and Shuck and a GTO sports car driven by Voelker. During this race, Parker, who was driving a pickup truck, hit his head on his windshield when he was forced to take evasive action to *496 avoid being hit by the racing automobiles. Parker pursued the automobiles to a small court into which the two sport cars had stopped, and blocked the single entrance with his truck. Parker approached the Corvette and, after shouting obscenities, reached into the automobile and struck Jack-man in the face. Jackman then exited his vehicle and engaged in a struggle with Parker. Voelker then caused everyone to fall to the ground when he jumped onto the men. While Shuck was trying to pull Voelker from the pile, Voelker gripped him on the shoulders and began to hit him several times. Shuck ran to Jackman’s automobile and obtained a baseball bat. Shuck returned with the bat and swung twice, hitting Voelker in the head once, thereby killing him.
Shuck was convicted of second degree murder and assault with intent to murder. In reversing these judgments the Court of Special Appeals held that the evidence generated a jury issue as to whether the doctrine of imperfect self defense might mitigate the homicide to voluntary manslaughter. The Court stated that Shuck was entitled to intervene in defense of his friend (Jackman) because the latter was neither an aggressor nor a mutual combatant. The Shuck court reasoned that a jury issue on this doctrine was generated because the defendant may have erroneously believed that he had a right to intervene in the defense of his companion and that he may have acted unreasonably in resorting to deadly force in what had been a non-deadly confrontation. In recognizing the doctrine the Court of Special Appeals noted that it was “highly persuaded” by the honest belief standard articulated by Professors Walter LaFave and Austin Scott in their treatise. See W. LaFave & A. Scott, Handbook on Criminal Law § 77, at 583-84 (1972). On this basis the intermediate appellate court reversed the conviction because the trial judge failed to instruct the jury on this issue of mitigation.
In Wentworth v. State, 29 Md.App. 110, 349 A.2d 421 (1975), cert. denied, 278 Md. 735 (1976), the defendant and her husband kidnapped a college professor from his home *497 and, later that evening, shot him to death. At trial, the defendant testified that she was “terrified” of her husband on this particular evening because he had accused her of having an adulterous relationship with the victim. As the result of her husband imbibing alcohol and ingesting drugs for a nervous condition, the defendant testified that he was “very paranoiac and was in another fit of rage[,]” and that she was afraid that she “would be killed at any minute.” Id. 29 Md.App. at 116, 349 A.2d 421. A jury convicted her of second degree murder, kidnapping, and related offenses. On appeal, the defendant contended that under Mullaney v. Wilbur, 421 U.S. 684, 95 S.Ct. 1881, 44 L.Ed.2d 508 (1975), the jury instruction unconstitutionally relieved the state of the burden of proof on the elements of the crime and any defense raised by the evidence. In a unanimous decision, the Court of Special Appeals agreed that the trial court’s instruction impermissibly placed the burden on the defendant to reduce the charge from murder to manslaughter by showing mitigation. Wentworth v. State, supra, 29 Md. App. at 115, 349 A.2d 421. Although the Wentworth court found that the evidence failed to generate the complete defense of duress, 5 it generated the mitigation defense of “imperfect” duress because the defendant may in fact have been coerced into killing the victim. In reversing the lower court the Court of Special Appeals remarked:
Recognizing that an “imperfect” defense of duress may not exculpate a defendant in an unlawful homicide case but may supply that mitigation necessary to lower the degree of guilt from murder to manslaughter, we conclude that the appellant here had a genuine jury issue as to mitigation. As a result, the jury instruction which *498 improperly placed upon her the burden of proving mitigation and which improperly relieved the State of its burden of proving the element of non-mitigation beyond a reasonable doubt requires a reversal under Mullaney v. Wilbur [supra,] analyzed in Evans v. State [, supra].
Id. 29 Md.App. at 121, 349 A.2d 421.
In the last of the 1975 spate of imperfect defense cases,' the Court of Special Appeals once again held that the evidence presented at trial generated the issue of mitigation by way of imperfect defense of habitation. Law v. State, 29 Md.App. 457, 349 A.2d 295 (1975), cert. denied, 278 Md. 726 (1976). Factually, the defendant, Law, got out of bed and went downstairs late one evening to investigate some noises outside. Law retrieved a shotgun he had bought for “home protection” two weeks earlier after his house had been burglarized. After hearing a scraping of his windowpane on his back porch and a voice saying “Let’s go in,” Law fired his shotgun toward the back door at waist level. The shotgun blast struck and killed a police officer who was trying to enter the house to investigate a suspected burglary attempt. Unknown to Law, his neighbor had summoned police to report a suspected burglary attempt.
Law was eventually convicted in a non-jury trial of second degree murder and assault with intent to murder. On appeal the Court of Special Appeals concluded that these facts, specifically Law’s mistaken belief that his home was about to be burglarized, raised the issue of mitigation by way of imperfect defense of habitation. As a consequence, the court reversed the judgments and remanded the case for a new trial. 6
A case decided after the Court of Special Appeals decision in the case sub judice discussed the doctrine of imperfect self defense. Cunningham v. State, 58 Md.App. 249, 473 *499 A.2d 40, cert. denied, 300 Md. 316, 477 A.2d 1195 (1984). In noting a recent “trend on the part of the defense bar to invoke this esoteric doctrine with inappropriate and promiscuous frequency,” the appellate court discussed at length that the purpose of this doctrine is “to recognize certain errors in judgment as extenuating factors.” Id. 58 Md.App. at 253, 473 A.2d 40. Unlike the cases above, the defendant in Cunningham failed to meet his burden of production to generate a genuine jury issue as to imperfect self defense or, for that matter, perfect self defense. Factually, the defendant armed himself with a shotgun and went looking for the person (the ultimate homicide victim) who had taken his moped earlier that day. Upon locating the victim, Cunningham produced his weapon and ordered some bystanders to clear the area. Although the victim was leaning on the moped and was “putting his hands by his pants,” Cunningham claimed that he thought that the victim was “grabbing for something” and had a “gun or something.” Based on these observations, Cunningham testified that he was “afraid that he would be killed.” Id. 58 Md.App. at 254, 473 A.2d 40. Cunningham then shot and fatally wounded the victim.
The trial court refused to instruct the jury as to either perfect or imperfect self defense, and the defendant was convicted of second degree murder. The Court of Special Appeals affirmed, concluding that the defendant was not entitled to an instruction on the defense of imperfect self defense. The intermediate appellate court reasoned that the partial proof of one element of perfect self defense does not necessarily give rise to an instruction as to imperfect self defense; rather, the
