Why I enjoy the KOTOR timeline in general, I find that it doesn't feel like morality is being shoved into your face much unlike the films. Instead, it's more realistic in its approach, the fact that the universe is full of shades of grays, not absolutes of black or white.
But personally, I find the Jedi hypocrisy to be a much bigger evil than anything displayed by Sith & their "pacifism" is a principled evil IMO.
