Mr. Noddy has a large and complicated family and thanks to his connections, I've known three child abusers. Dlowan is absolutely right. They seem "normal". They have had confusing and unpleasant childhoods. All three felt they were doing favors for the children they molested and insisted that they acted out of love.
By the way, what logic are you talking about? The part about not killing people? Or the part about not talking about guns on a thread about child porn?
