I know we have erratic trait. But are their any mods that are safe that have certain types of erratic/crazy behavior?
Such as a sim who is gets possessive or obsessed with someone, or a off the wall trait, where their actions and reactions and moods are just random, where they all the sudden get crazy angry for no reason.

Are their any different types of evil traits too? I hate to admit it but adding villains to the sims stories does make it more fun and interesting.
