After reading some of the posts, and the article, I was reminded of the daughter of a friend of mine. The friend is PG. The daughter was similar as a child to one described and the father actually thought his daughter would grow up to be a serial killer.
On the contrary, as she finally got through her teens, she made different choices. Whether she is still unempathic, I do not know, but she behaves and is managing her life. Perhaps, many of these highly intelligent psychopaths do manage the "bad" behaviors as they get older and blend in.
