They know it's wrong ippy, they justify their actions to themselves and often mix with people of like mind who reinforce what they choose to believe. It's not an illness.
I'll have to read a bit more about Mr Freud before I make any more comments about him.
Later: Just read the latest. It certainly does appear that he sexually abused a couple of girls, one of whom was in his care - later on he said he ''loved'' her and that she was a ''sensuous little girl''
. His wife doesn't seem to have known anything about it which does not surprise me, it is amazing what can go on in the lives of loved ones that is kept hidden and she wouldn't have even thought of such a thing. People didn't years ago.
The McCann link is tenuous. Little Madeline was only four. He was living in the vicinity and befriended the family after her abduction but I doubt there is any more to it.
