Stephen King's facial expression is terrifying and makes the hair stand up on the back of my neck.

Regarding how he writes about children, this should explain it:

King was interviewed for an article years ago. I wish I could track it down to get the exact quote, but basically he said he was out of control with drugs due to some kind of past trauma in his life. After he married and had children he said he began having evil thoughts of harming the children, so in order to keep himself from doing horrible things to them, he puts those ideas into his novels as a type of catharsis.

Per one article:

"In 1987, his wife Tabitha King staged an intervention by dumping out the contents of his garbage can in front of their friends and family. The trash can effectively said all that needed to be said; according to King, it contained, “beer cans, cigarette butts, cocaine in gram bottles and cocaine in plastic baggies, coke spoons caked with snot and blood, Valium, Xanax, bottles of Robitussin cough syrup and Nyquil cold medicine, even bottles of mouthwash. Tabitha threatened to leave if he didn’t get sober. He would later say that he doesn’t even remember writing some of his books; he was that much off his face."
