I mean evil to the core. Without the hope of rehabilitation. The kind of kids that not only you wouldn't want to have your kids or pets around, but you yourself would think twice about letting them out of your sight? What do you think? Me, I've known of a couple of kids who tortured animals and did Satanic things with them. From what I know, they grew up to be adults who've spent time in prison. Then there's those two kids in England I think that took the toddler and killed him. Kind of like that movie The Good Son, with Macaulay Culkin.
