Thing is if you are going to be evil, you need to be truly evil. basic thug is not evil. I am talking about having a poor smuck chained to the wall and peeling one layer of flesh off at a time, then use a rock salt grinding wheel to whittle his or her limbs away, just for fun.
True evil is to diabolically plot out the fall of someone, not out of gain but for the pleasure of seeing their lives crumble before them as the take their own life in the utter despair that you cast them in.
Of course such situations will never happen in this game.
