and not for any justifiable reason.

Really? I've always thought the PT was the perfect opportunity to explore what would bring a hero down to the point where he becomes Darth Vader. It seems like a real shame to miss out on that.

Perhaps I phrased it badly.

I want to avoid a situation like in ROTS (or the EU) where going to the Dark Side is a valid and justifiable choice.

The Dark Side isn't cool powers to do good with, where you can do a cost/benefit analysis. It's evil, easier, more seductive, and will dominate your destiny. You can't start down that path.

Anakin should be driven to the Dark Side by succumbing to his weaknesses (I'm working on a combination of anger, impatience, and jealousy... a little like Luke has, only worse), not by consciously acting out of altruism, and not by being tricked.
