Scale and criminals

Stone researched hundreds of killers and their methods and motives to develop his hierarchy of "evil".^[3] The scale ranges from Category 1, those who kill in self-defense, to the Category 22, serial torturer-murderers. Dr. Stone described the categories of the scale in his book The Anatomy of Evil, published in 2009.^[4] In a follow-up book, The New Evil: Understanding the Emergence of Modern Violent Crime, published in 2019, he and co-author Dr. Gary Brucato, a clinical psychologist and researcher, break down the individual categories of the scale in detail.^[5]

Neurologists, psychologists, and other forensic psychiatrists are interviewed on the show in an attempt to examine and profile the minds of notorious killers. Partial re-enactments are shown along with news footage, evidence, and reports from locals. Neurological, environmental, and genetic factors are examined to help determine what drives a person to kill. Background history and pre-meditation are considered when placing an individual on the scale of evil. The show indirectly deals with the concepts of morality and ethics.
