I knew a guy from high school who is a cleptomaniac. If you asked him about it, he would say he stole and robbed from people because he always felt that way compulsively [he was aware of his problem but couldn't stop it].
He came from a very large catholic family [7 kids] of overwhelmed parents and he was smack in the middle of the 7 kids. I'd say, just on an educated guess, that he learned that stealing [when he got caught] got him attention from his parents he didn't otherwise get. Funny how when he stole things, he got caught more often than a practiced thief should..
Because of the pleasurable association with getting attention, conditioned and affixed to stealing, he has difficulty controlling the compulsion. I suppose if put to a jury, he would swear he was "born that way".
We shouldn't judge this tranny for robbing. He was probably born in the wrong legal system and needs to change how society views his mental condition. We are such bigots...
