I disagree with this appraisal, but I also have a question: do you think sociopathy is something people or born with or that they learn? If people are born as sociopaths, it's hardly fair to kill them for something they can't help. I'm not excusing murderers or rapists - I do think violent felons should be gaoled, but I just don't think the death penalty is much of a solution. Sure, it deters the one person who is stopped, but who else?
