Psychopaths are all around us. Who are they? What are they? What makes them feel no empathy for other human beings, seeing them only as objects to manipulate and control? In Episode 2 of Sword and Scale, we examine these questions and here from one of the world's leading neuroscientists in this field Professor James Fallon, who is not only an expert in the field of psychopathy, but also exhibits many of the traits of a psychopath himself. We also hear from actual psychopaths in their own words, including a chilling interview conducted of a serial sex offender by Dr. Anna Salter. Also, we'll play part of the final interview of one of the twentieth century's most infamous serial killers: Ted Bundy. The lack of empathy or remorse in their voice as they share the details of their horrific actions will probably turn your stomach, unless of course you're also a psychopath. Very special thanks to James H. Fallon, Professor Emeritus, Anatomy & Neurobiology School of Medicine, University of California, Irvine.
