The retributive theory allows criminals to be punished without reference to the social consequences of punishment. But suppose that, for a variety of reasons, punishment significantly increases the crime rate rather than reduces it. Mentally unstable persons might be attracted by the prospect of punishment. Punishment might embitter and alienate criminals from society and increase their criminal activities. If punishment had these and other bad effects, utilitarians would renounce punishment in favour of some other more effective approach for dealing with offenders. But retributivists are still committed to punishing criminals. The effect of retributive punishment in such a situation is that there will be an increase in the number of innocent victims of crime. For whose benefit is punishment to be instituted? Surely not for the benefit of law-abiding citizens who run an increased risk of being victims of crime. Why should innocent people suffer for the sake of dispensing retributive justice?
