To complete that point,

How would you explain an irrational and compulsive desire to create an artificial state of anger, so as - perhaps - to benefit from the 'positive' effects eg sense of catharsis, power, superiority, or ultimately (and being involved with kids you'll understand the pull of this last one) attention.

All this despite the knowledge (that experience brings) that ultimately all it does is give you a headache at best and get you into serious trouble at worst.
