IIRC those "principles" were pretty barebones. I think it was just the deathfog with Ifan (and Beast? Maybe Sebille?). To me, with one action that might make your team stop, you could turn altruistic heroes into self-serving sadists pretty easily.
Whom are you talking about? There were total 0 of altruistic heroes or self-serving sadists at the start of the game. All morally grey with certain ways to turn them in one direction or another.
