Psychopaths live among us as our friends, family members, co-workers, or even lovers. While many are skilled at pretending to be normal people, their lack of empathy, calculating, manipulative, impulsive, narcissistic, and even murderous natures set them apart. This 8-episode true-crime series analyses some of the most notorious killers in modern history to explore the signs of psychopathy that they displayed. Upcoming episodes include an interview with John Hummel, who bludgeoned, stabbed and burnt his pregnant wife, 5-year-old daughter and his father-in-law.
