Even as an Arabian Muslim, I say that he was guilty and should be punished for all the humanity crimes he made.
Seconded. What pisses me off is how he can still try to pretend that he was a religious person after all this. "God is greater than the occupier"? Damn right, why didn't you think of that when YOU were the occupier? How can someone pretend to be religious when the very crime that he was punished for was ordering the murder of 148 of his brothers in faith, for practicing a slightly different variant of what he should have been practicing?
I think he should be executed by beheading. My belief, as far as "why give him a quick exit from the world?" is concerned, is that he should be executed under the punishment of murder. If you don't give people enough discouragement, they will continue to abuse the generosity and ruin society. Sometimes, as much as you hate it, you have to amputate a limb in order to save the rest of the body. That's what I think at least.
