17 of 17The Reaper (C. Thomas Howell), Criminal Minds
The Reaper was a narcissistic sociopath who at one point killed 20 people in three years and severely injured George Foyet, who survived 67 stabbings one night. Crazy, right? Even crazier, Foyet wasThe Reaper, meaning he pretended to be a victim and stabbed himself (!) to manipulate the police. Always one step ahead, The Reaper attacked Hotch at his home, stabbing him nine times, but Hotch finally got him months later by beating him to death -- but not before The Reaper killed his ex-wife Haley.
