Coming to the actual debate, about whether capital punishment should be abolished, both sides make compelling arguments. I personally am of the opinion that the above should be abolished.
It is not incorrect when people who support the idea, insist that continuing to support criminals already proven guilty, strains the tax payer and resources, especially since releasing criminals from the system, is not an option keeping the gravity of their crimes in mind.
Capital punishment is often justified with the argument that by executing convicted murderers, we will deter would-be murderers from killing people. However, statistical evidence doesn't confirm that deterrence works. In fact, some may have not be capable of being deterred either because of mental illness or because the crimes are committed in an emotional state where the criminal did not give a thought to the consequences of his actions. When one thinks about it no one knows whether the death penalty deters more than life imprisonment.
Another important thing to keep in mind is timeliness. Deterrence is most effective when the punishment happens soon after the crime e.g. a child learns not to put their finger in the fire, because the consequence is instant pain.The more the legal process distances the punishment from the crime - either in time, or certainty - the less effective a deterrent the punishment will probably be.
This argument also states that real justice requires people to suffer for their wrongdoing, and to suffer in a way appropriate for the crime. Each criminal should get what their crime deserves and in the case of a murderer what their crime deserves is death.
It's often supported with the argument "An eye for an eye". But this is a classic case of perceiving the scriptures to suit one’s need. In fact the Old Testament meaning of "an eye for an eye" is that only the guilty should be punished, and they should punished neither too leniently nor too severely.
The main argument that retribution is immoral is that it is just a sanitised form of vengeance. Scenes of howling mobs attacking prison vans containing those accused of murder on their way to and from court, or chanting aggressively outside prisons when an offender is being executed, suggest that vengeance remains a major ingredient in the public popularity of capital punishment.
It's argued that retribution is used in a unique way in the case of the death penalty. Crimes other than murder do not receive a punishment that mimics the crime - for example rapists are not punished by sexual assault and people guilty of assault are not ceremonially beaten up.
Some well-known philosophers and thinkers have argued that the justice in the case of the death penalty was not fair, because the anticipatory suffering of the criminal before execution would probably outweigh the anticipatory suffering of the victim of their crime.
Others argue, on similar grounds, that the retribution argument is flawed because, the death penalty delivers a ‘double punishment’; that of the execution and the preceding wait, and this is a mismatch to the crime. Many offenders are kept 'waiting' on death row for a very long time; in USA the average wait is 10 years.
Civilised societies do not tolerate torture, even if it can be shown that torture may deter, or produce other good effects.In the same way, many people feel that the death penalty is an inappropriate punishment for a modern civilised society to respond to even the most dreadful crimes.
Because most countries - but not all - do not execute people publicly, capital punishment is not a degrading public spectacle. However, it is still a media circus, receiving immense publicity, so that the public are well aware of what is being done on their behalf.Also, this media circus takes over the exhibition of public execution. Thus, the idea of teaching the public lessons about justice, retribution, and personal responsibility for one's own actions seems to take a back seat.
Also, there are rare cases in history where innocent victims were awarded the death penalty because they did not enough evidence to prove their innocence, or because they had a poor defence. Thus, while the benefits of capital punishment are debatable, in these cases, where the person is a victim of consequences, the punishment is unacceptable.
Another reason why prison sentence merits the use of capital punishment is because, while the punishing the criminal does nothing to help the people surviving the victim; it also takes away from the culprit, a chance to repent for his mistakes.
Thus, at the risk of sounding idealistic, I am of the opinion that capital punishment must be abolished.
