Death Penalty

But does killing someone undo the crime? Killing someone to make a family feel better is dumb because you're just in turn hurting another family(the family of the person being put to death.)

There are other less barbaric ways for a family to cope with the loss of a loved one than demanding someone be put to death for it.

I understand that there are emotional reasons behind the death penalty, but that's just not good enough when it comes to deciding whether someone should live or die. That should not be based in emotion.
