Depraved indifference

In United States law, depraved-heart murder, also known as depraved-indifference murder, is an action where a defendant acts with a "depraved indifference" to human life and where such act results in a death. In a depraved-heart murder, defendants commit an act even though they know their act runs an unusually high risk of causing death or serious bodily harm to someone else. If the risk of death or bodily harm is great enough, ignoring it demonstrates a "depraved indifference" to human life and the resulting death is considered to have been committed with malice aforethought. In some states, depraved-heart killings constitute second-degree murder, while in others, the act would be charged with varying degrees of manslaughter.

If no death results, such an act would generally constitute reckless endangerment (sometimes known as "culpable negligence") and possibly other crimes, such as assault.

Depraved-heart murder is the form of murder that establishes that the willful doing of a dangerous and reckless act with wanton indifference to the consequences and perils involved, is just as blameworthy, and just as worthy of punishment, when the harmful result ensues, as is the express intent to kill itself. This highly blameworthy state of mind is not one of mere negligence. ... It is not merely one even of gross criminal negligence. ... It involves rather the deliberate perpetration of a knowingly dangerous act with reckless and wanton unconcern and indifference as to whether anyone is harmed or not. The common law treats such a state of mind as just as blameworthy, just as anti-social and, therefore, just as truly murderous as the specific intents to kill and to harm.

The common law punishes unintentional homicide as murder if the defendant commits an act of gross recklessness. A classic example of depraved-heart murder under the common law is in the case Commonwealth v. Malone, a Pennsylvania case in which the court affirmed the second-degree murder conviction of a teenager for a death arising from a game of modified Russian roulette in which each player pointed and fired the gun at the other, eventually resulting in the death of one of them.
