this is a tough issue. i oppose killing him, because then we're just like him. How about a jail cell and some bread and water? based off the fact that he didnt actually kill anyone, the death penalty doesnt seem to fit the crime.
I don't think the argument of "he didn't actually kill anyone" is exactly a very good thing: he has nonetheless been the mastermind behind thousands of deaths. Was Hitler completely innocent? I don't think he ever actually killed anyone.
I disagree that killing him will make us just like him, because we'll be killing Osama bin Laden, and not, you know, thousands of innocent people.
