I was just discussing this with my fiance today on the way to her mom's, how Lucas did a very good job of setting up how dictators and "evil" people come to be. You don't just wake up one morning and decide to kill your friends. The truth is, evil people think they're right and just or they wouldn't do what they do. A history teacher I had in high school put us through a very eye opening lesson. She held a mock election under the guise of teaching us about democracy, and had two canidates. One was very appealing, had very well thought out reasons for change and solutions to problems. By the end of the election, this canidate won, and ended up being Hitler. The other was Roosevelt and our teacher used their exact election strategies to show us that if some one comes to you with all this confidence, and their solutions to your problems seem really solid and well thought out, you'd be more than willing to go with that thought process, and in the case of Hitler, end up being led down a steadily growing path to a more evil life with out even knowing it. And that's really what happened to Anakin and the Republic, they believed Palpatine and before they knew it, they were the bad guys and they never even realise it until its too late. I think that's one part of Star Wars Lucas more than handled correctly. I just hope Joe Moviegoer can see past their own movie plots long enough to understand the more real world honesty in this portion of the story, and not just be mad cuz Anakin doesn't enjoy and revel in being "bad" rather than commit wrong in the guise of righteousness.
