Retributive Justice

Retributive justice is a theory of justice that considers punishment, if proportionate, to be the best response to crime. When an offender breaks the law, s/he thereby forfeits or suspends her/his right to something of equal value, and justice requires that this forfeit be enacted. This is sometimes taken to mean that justice involves seeking vengeance on behalf of the aggrieved party, or society as a whole.

In ethics and law, "Let the punishment fit the crime" is a principle aphorism that means the severity of penalty for a misdeed or wrongdoing should be reasonable and proportionate to the severity of the infraction. The concept is common to most cultures throughout the world and is evident in many ancient texts. Its presence in the ancient Jewish culture is shown by its inclusion in the law of Moses, specifically in Deuteronomy 19:17-21, and Exodus 21:23-21:27, which includes the punishments of "life for life, eye for eye, tooth for tooth, hand for hand, foot for foot." That phrasing in turn resembles the older Code of Hammurabi. Many other documents reflect this value in the world's cultures. However, the judgment of whether a punishment is appropriately severe can vary greatly between cultures and individuals.

Proportionality requires that the level of punishment be scaled relative to the severity of the offending behaviour. However, this does not mean that the punishment has to be equivalent to the crime. A retributive system must punish severe crime more harshly than minor crime, but retributivists differ about how harsh or soft the system should be overall.

Traditionally, philosophers of punishment have contrasted retributivism with utilitarianism. For utilitarians, punishment is forward-looking, justified by a purported ability to achieve future social benefits, such as crime reduction. For retributionists, punishment is backward-looking, justified by the crime that has been committed and carried out to atone for the damage already done.

Depending on the retributivist, the crime's level of severity might be determined by the amount of harm, unfair advantage or moral imbalance the crime caused.
