The death penalty has its uses. Consider mass-murderers, serial rapists and other criminals. These criminals are often punished with life-sentences or stays at psychiatric wards (which are infamous for almost never releasing 'patients'). How is the death penalty crueler than the thought of living in a cell for the remainder of your life? The death penalty, when used in conjunction with rehabilitation and other methods of dealing with criminals, can be an effective deterrent, and can also bring peace to victims' families. The death penalty holds an important role in the criminal justice system.
