I think we're arguing slightly different points here. Where as you're arguing IN-world, I'm coming from a basic film mechanics OUT-of-world standpoint.

I say this because I don't necessarily disagree with anything you've just said, BUT I still believe that Lando is portrayed as a bad guy in the film, until he turns the tables and offers his help. Again....film mechanics, not an in-world explanation.

In-world, he has his reasons and they may in fact be well-intentioned ones. Out-of-world, he still causes harm to the protagonists by joining forces with the main villain.

But I can definitely agree to disagree....especially seeing as this IS an argument of semantics seeing as Lando's alignment was not at all the point of my original post, but rather the argument against idea that there were no characters in SW who CHANGE alignments. Lando was only one of the examples, and some of you disagree with that particular one.
