A child featured on an episode of Dr. Phil today is basically a living, breathing contraceptive: He's just totally out of control. He throws fits, screams, cries, scratches, scars himself, spits on people, barks for hours at a time, runs to the kitchen for sharp objects when he's upset, and has even threatened his siblings with a butcher knife. Worst of all, he tells his mother on a daily basis that he wants to kill her, and goes into detail, telling her he will eat her carcass. He has been diagnosed as autistic, which surely must make things more complicated, but his disorder doesn't really get him of the hook for the death threats, in our book.
