Who do you think should recieve the death penalty?

I have a differant opinion on the matter. I think some people truely deserve to be put to death. People with no souls, have no regrets of the crime, and who would do it all over again. Because if they are let out, they WILL do it again. Prisons are explensive. The avarage cost of an inmate per year is $27,134. Do you know how many schools, hospitals, ect. really need that money? Those nasty perverted MONSTERS don't deserve our tax money that we work hard for. I'm not saying all felons, just multiple repeaters. And ONLY violent crimes. I would feel bad if some guy who just needed some money to support his family was killed. But Serial Rapists and murderers, (and anything involving children) Should get no sympathy. That is my views T_T
