How can we Justify Punishment?

We generally accept that people who commit serious wrongs should be punished, yet punishment deliberately inflicts suffering, deprivation or hardship on a person. In most circumstances, deliberately harming another person would itself be considered wrong. The central question is therefore why such harm can be morally justified when imposed by legitimate authority upon someone who has committed an offence.

Retribution vs Consequences

Retributivists argue that punishment is justified because wrongdoers deserve a proportionate response to their wrongdoing. Punishment is therefore primarily concerned with justice and desert, rather than with producing future benefits.

Consequentialists, by contrast, maintain that punishment can only be justified by its beneficial consequences, such as deterrence, incapacitation, rehabilitation or the protection of society.

This raises a fundamental question: should punishment be imposed because someone deserves it, even when no useful consequence will result, or is suffering only justified when it produces some further benefit?

Punishment vs Revenge

Closely related is the distinction between punishment and revenge. Both involve responding to wrongdoing by causing suffering, but revenge is normally a personal response, whereas punishment is an institutional response governed by law and due process. The state attempts to replace private retaliation with an impartial system of justice. Nevertheless, the fact that punishment is administered by the state does not, by itself, establish that it is morally justified.

Punishment should be proportionate

Proportionality is another central issue. Even if offenders deserve punishment, how severe should it be? What determines whether imprisonment, a fine, community service or another penalty is appropriate? The seriousness of an offence, the offender's intentions, circumstances and degree of responsibility all appear relevant, but there is no simple method of determining the precise punishment deserved.

Conflict between the aims of punishment

Punishment also has several possible purposes. It may deter crime, incapacitate dangerous offenders, rehabilitate criminals, protect the public, express society's condemnation of wrongdoing or affirm the rights of victims. These purposes can conflict, particularly when a punishment that seems deserved is unlikely to produce any useful future consequence.

The problem of state power

Punishment raises questions about state power and responsibility. Since the state possesses considerable coercive power, safeguards are needed against wrongful convictions, excessive sentences and inhumane treatment.

The problem of personal responsibility

At the same time, punishment presupposes that individuals are responsible for their actions. Understanding how behaviour is influenced by upbringing, circumstances and psychological factors therefore raises difficult questions about free will, responsibility and desert.
