In our day death is usually administered in private by relatively painless means, such as injections of drugs, and to that extent it may be less effective as a deterrent. Sociological evidence on the deterrent effect of the death penalty as currently practiced is ambiguous, conflicting, and far from probative. Some proponents of capital punishment argue that capital punishment is beneficial even if it has no deterrent effect.
If we execute murderers and there is in fact no deterrent effect, we have killed a bunch of murderers. If we fail to execute murderers, and doing so would in fact have deterred other murders, we have allowed the killing of a bunch of innocent victims. I would much rather risk the former. This, to me, is not a tough call.
Of course capital punishment doesn't rehabilitate the prisoner and return them to society. But there are many examples of persons condemned to death taking the opportunity of the time before execution to repent, express remorse, and very often experience profound spiritual rehabilitation. Thomas Aquinas noted that by accepting the punishment of death, the offender was able to expiate his evil deeds and so escape punishment in the next life.
This is not an argument in favour of capital punishment, but it demonstrates that the death penalty can lead to some forms of rehabilitation. Many people don't think that this is sufficient justification for taking human life, and argue that there are other ways to ensure the offenders do not re-offend, such as imprisonment for life without possibility of parole.
Although there have been cases of persons escaping from prison and killing again, these are extremely rare. But some people don't believe that life imprisonment without parole protects society adequately. The offender may no longer be a danger to the public, but he remains a danger to prison staff and other inmates. Execution would remove that danger.
This is a rather flimsy argument, because every family reacts differently. As some families do not feel that another death will provide closure, the argument doesn't provide a justification for capital punishment as a whole. Plea bargaining is used in most countries. It's the process through which a criminal gets a reduced sentence in exchange for providing help to the police. Where the possible sentence is death, the prisoner has the strongest possible incentive to try to get their sentence reduced, even to life imprisonment without possibility of parole, and it's argued that capital punishment therefore gives a useful tool to the police.
This is a very feeble justification for capital punishment, and is rather similar to arguments that torture is justified because it would be a useful police tool.
