The death penalty isn't about justice, it's about retribution and I do not agree that retribution should be underpinning any objective and fair justice system...it simply isn't necessary to kill someone, they can be effectively removed from society and doing more harm in other ways without the need to kill them. Even in cases of indisputable guilt and lack of remorse doesn't mean that the lack thereof is permanent or that society should have the ability to take the life of someone simply as revenge against someone who took the life of someone else. Death should only be advocated when all other avenues and solutions are exhausted and even then we should think twice.
I suppose the only time you could advocate execution would be in some kind of hostage situation, but would it be execution. Taking a bad life to save a good life so to speak, would it still be execution or can it be only called execution as a result of something a person had been convicted of.
I would not, it would have screwed up my life. It would have been probably an exhilarating relief at the time but on reflection I would not have wanted to look back and see myself doing something so barbaric.
I think what some are missing here is the point that a death sentence is a deterrent to reasonable people. These kinds of people are not reasonable, they either have mental issues that cause extreme acts for no apparent reason or they are just so predisposed to violence no punishment could ever dissuade them. Even a normally passive person could be pushed by reason of circumstance to kill, this again is a situation where any deterrent would not work because in a crime of passion or the heat of the moment punishment will only be remembered after the act. When feelings are running so high all logic and reason is forgotten.
