I disagree with the death penalty.
Its original purpose has failed. The death penalty was created as a deterrent for crime. So far, this theory has been proven wrong. Statistics show that states with the death penalty have just as much crime as those without, if not more. Furthermore, there have been an increasing number of wrongly convicted criminals leading to more and more innocent deaths, found out too late to be reversed.
Life in prison would be a much more brutal punishment in which guiltiness is gnawing you inside out.

Oh, and I'd like to point out that a lot of you for the death penalty make the money argument that the government doesn't have enough money to keep them there.
But in actuality, it costs more to send the person to death row then it does to keep them in prison.
