One of the things the disturbed character knows very well about relatively well-adjusted or “neurotic” individuals is that they hate to see someone else suffer. Not only that, they hate it more to think of themselves as the cause of someone else’s suffering. That’s why playing the victim role is such an effective tactic. Especially when they’re confronted about their own malicious behavior, disordered characters will try and turn the tables by trying to get you to see them as the injured party.
