Cannibals and evil cult killers

This book delves into the gruesome side of human nature. It describes brutal, horrific murders where people have been totally brainwashed by a leading cult figure. They prey on their victims leaving a bloodbath behind them. It reveals some of the dark secrets that drive these people to commit such heinous crimes. Was the Easter Islanders' cannibalism exclusively a religious rite or the expression of an urge for revenge? Or was it induced by a simple liking for human flesh that could impel a man to kill for no other reason than his desire for fresh meat.
