Society: On the Scale of Evil, Where Do Murderers Rate?

This'd be very interesting if it'd weren't restricted to murderers.

Inspired by the structure of Dante's circles of hell, Stone has created his own 22-point "Gradations of Evil" scale, made up of murderers in the 20th century. "I thought it would be an interesting thing to do," he says.

His scale is loosely divided into three tiers. First are impulsive evil-doers: driven to a single act of murder in a moment of rage or jealousy. Next are people who lack extreme psychopathic features, but may be psychotic — that is, clinically delusional or out of touch with reality. Last are the profoundly psychopathic, or "those who possess superficial charm, glib speech, grandiosity, but most importantly cunning and manipulativeness," Stone says. "They have no remorse for what they've done to other people."
