I don't know. I know this may sound cruel, but I personally think it would be better to let him rot in jail or something, torture him. I think that killing him was the easy way out.
I heard some where that he said that if he died he would die a mayter (sp?). Why give him that honor that he wants?
Alot of people suffered greatly under his rule.
There might be some backlash after his death, but i'm not to savy on the going about on Iraq, so I can't put much input in that area.
