We disucssed this in class a few weeks ago, and I’ll repeat what I said then: I think it’d be much more effective to let him rot away in a cell. That’d be the former dictator with no dignity, not honour, nothing left - then he wouldn’t become a martyr-esque person for those who still support him, something he now very well may become. It’d be so much more effective to show that “see, we know what he did - this is how he ended up. And, we’re not like him”.
I’d say that a megalomaniac like a former dictator probably is would suffer more from being powerless than hung.

This is the mistake people are making, he was tried by the Iraqi government, not the U.S. government.

I never said they would feel guilt, but he’d surely be upset if he had an “unpleasant” time in prison for the rest of his life.

I’m sort of iffy on the death penalty. I’d hate to see someone who people thought was guilty, but was really innocent have to die for something that they did not do, but yet for someone who has obviously killed so many people to get to live out the rest of their life when they unhesitatingly took the lives of other people seems a bit unfair to me also. Yes, they they can live out the rest of their life in jail and feel ‘guilty’ about it, but these people are sociopaths, for the most part. They have no empathy or remorse. How are they even supposed to begin feel guilty?
