Actions may speak louder than words, but do they speak louder than motivations?
In a game world, what's in one's heart may be as important, or moreso, than what they do. If you do the right things for the wrong reasons, or do the wrong things for the right reasons, it may be possible that magic, or cosmic karma, or technological mind reading can determine your true intentions. And the gods, or the fates, or even the secular authorities might determine justice based on that, rather than what you did.
Imagine a world a bit like Minority Report, but where law enforcement can determine your motives without fail, and where what we would consider the most heinous crimes can be forgiven if your heart is pure. And where you can be punished for being evil, no matter if you've actually done anything "wrong" or not.

R2-D2: Wow, I didn't think someone like Vader could be redeemed.
Chewbacca: Doesn't that kind of go against the premise of your job?
R2-D2: I mean in game morality, not the real world.
Luke: Anyone can be redeemed, if they follow the Path.
Chewbacca: Even Anakin?
R2-D2: No, he completed the Path to the Dark Side. You can't complete two Paths, otherwise what's the point?
C-3PO: If you reject who you were, maybe you could start a new Path.
Han: It depends where you start from. Anakin was always evil, really.
GM: After someone injected him with midi-chlorians...
Leia: Right, and Padmé was really a good person. She was driven by love, for the people, and then for Anakin.
C-3PO: Vader did terrible things though.
GM: The road to Hell is paved with good intentions...
Chewbacca: And the Path to the Light Side is apparently paved with choked minions and the dust of shattered planets.
Padmé: Nobody's perfect.
