I used to be for the death penalty, but once DNA started proving many people weren't the real killers or whatnot, I am neutral on the idea.
I believe it would be better to let someone sit in a jail cell for the rest of their lives, thinking about what they did. I do feel we make it easy for people in jail though. They get cable tv, internet, books to read, and so much more. They are in jail to learn about their mistakes, and they should not be given things many people cannot afford themselves. Make them sit in a jail cell all day looking at the wall.
