Followup

So the dude kills three people in Idaho, kidnaps the kids for sex toys, abuses and kills the boy, and abuses the girl. That's a whole heap of evil by itself.

Now we find out that he's been bragging to the little girl about all of his twisted deeds while he has her captive?

That poor girl is more than scarred for life. She would probably have been better off if he had killed her too.
