First, make sure that what you’re dealing with is in fact a child and not just, say, a slow-growing adult who shaves his pubic hair to appear prepubescent (The Next). Second, it’s important to determine what kind of homicidal child you have: a) adopted (The Godsend, 1976) b) chemically altered (Childmare, 1980) c) possessed (The Moonchild, 1978) d) reincarnated (The Children, 1982) e) poorly parented (Mama’s Little Girl, 1983) f) inappropriately violent for no good reason (Prissy, 1978) g) in possession of psychic powers (The Savior, 1978) h) Satan spawn (Seed of Evil, 1988)
