This is only your conclusion, not the game's. KOTOR2 isn't an ego trip where you save the kingdom and get the princess. And i don't even think there's "right" and "wrong" in the game. If Kreia or someone else say something, it doesn't automatically means that that what devs want you to believe. It is a game that challenges you to think, instead of blindly excepting some in-game logic of what's good and bad. Saying that that is what the game is about is entirely wrong simply because it never provides you with any kind of answers.
