I actually saw Bush speak and briefly met him at an event in Columbus during his second campaign. He spoke much more elegantly and better than people have him credit for, and was a much warmer and intelligent man than is thought. He seemed like a nice enough guy.
From his actions and what he has said in the subject since, I think he got tricked into the war with bad Intel and advice, and I think it weighs upon him greatly. I think he wanted to believe, and his advisors knew this and played to it.
And that is almost worst. He made a mistake, and he killed hundreds of thousands of people. By mistake. Whoops. Evil we can understand. But someone trying to do the right thing and doing the very worst thing? That is harder.
