Saddam Hussein was recent sentenced to hang by an Iraqi court. I opposed to his hanging - right now or reasonably soon. The following trials will continue with him in abstentia. I really think that he would be better off learning and knowing the reasons for his death other than just the one reason.
While I'm not in opposed to the death penalty, I can't find a reason why it would be better to kill a person versus letting them sit, in prison or solitary confinement and sit and brew over what he had done and knowing that there would be nothing else than they could do - either for or against other people.
The only flaw in this penalty is that it depends on a person actually having a conscience, it depends on a person actually being capable of being sorry for what they had done.
