In the book In Cold Blood, Dick and Perry are a pair of murderers that kill multiple people. Their motive for breaking into the home was so they could steal money and they both claim that they did not intend on killing anyone. But was there really a reason for them to kill not just one of the members of the family but multiple of them? In the Ted Talk, Jim Fallon explores the different aspects, traits, and events that could lead a person to be a psychopathic murderer. Jim says that a person's genes, environment, or brain damage mixed with the right timing can lead to psychopathic ways. For example Perry Smith came from a very dysfunctional family and home. As a child he had to deal with abuse and go through the pain of two of his siblings committing suicide and his mother dying from choking on her vomit. All of these events led him to become a very immature person with poor mental health. Jim also explains that most psychopaths have a very traumatic event that happens to them when they are young, which Perry has happen to him when his family members died. This Ted Talk gave insight on why Dick and Perry might have killed the people.
