"Reporter: "Sir, why did you risk your life to save this woman from her attacker?"
Heroic psychopath: "Because I wanted to fight some-- Err... Because she needed to be rescued."

Kid I am mentoring has multiple diagnoses, and I believe one may be aspd. I believe he is actually a multiple (DID) but they often get these multiple diagnoses. Anyway, he is one that would rescue because he wants to fight someone due to boredom. But he isn't lacking in empathy attachments. Would also rescue someone he cared about.
