I agree with Helois, the death penalty is wrong, for many reasons:
1 - The point of prison is to right what you did wrong, and to sort yourself out, dying doesnt accomplish that, does it??
2 - If their is a mistake, thats an innocent life there, could you be the guy who put him down to find him innocent??
3 - Psychological effects on the guards as well, dont forget im sure thier effected.
4 - Most murderers have a psychological problem, why not treat it? Thats like saying everyone with Schitzophrenia should die... (sounds kinda pathetic now, right?)
5 - Its ethically wrong...
6 - It goes against everything our societies are supposed to stand for.
7 - Think of it this way, if a child does something wrong, and the parent slaps it for doing so, when the child feels someone else has done wrong, it will slap them... a similar effect works with the death penalty. If someone does something wrong, and the government kills them, it encourages people to kill if they feel others have done wrong... is this not a HUGE issue???
