Sociopath Versus Psychopath Anders Breivik (left), who murdered dozens of children at a summer camp in Norway, would be considered a sociopath, according to neuroscientist Jack Pemment (2013). His horrific acts were in response to his extreme nationalistic beliefs, and he saw himself as a martyr for his country. Breivik seems to have a sense of morality, although it is tragically misguided. The serial killer Israel Keyes (right), who buried weapons and shovels to dispose of bodies all over the U.S. to facilitate his homicides, is likely a psychopath. After his arrest, he told investigators that for most of his life, he thought that all people just pretended to be nice. Keyes seems to have no sense of morality whatsoever.
