Should the Death Penalty be used to Punish Violent Criminals?

                I do not think the death penalty be used to punish violent criminals because they do not have chance to look back their fault and victims cannot see they are changing. If they got death penalty and they died right away than victims have no chance to see that they are have hard time for punishment because they died. This death penalty is useless to victims in my opinion.

                I also think Criminals likes the death penalty punishment because they really do not have to do anything except close their eyes. For that punishment some of victims like criminals’ death but some also want to see that they have hard time doing the punishments. So I think they use the death penalty as for criminals who did multiple times of problems.
