Domestic Violence, Relationship Violence and Dating Violence all involve patterns of behavior in which someone uses physical violence, intimidation, isolation or other forms of abuse to harm you. However, according to behavior psychologists, acting out on these negative behaviors can be either impulsive or evolutionary. One psychologist who believes a person’s violent behavior is an evolutionary process is Louis Schlesinger, who is a professor of psychology at John Jay College of Criminal Justice and an expert on serial sexual murder. As it relates to serial murderer Jeffrey Dahmer’s violent behavior, Schlesinger said that, “When you do something like Dahmer did, you don’t just one day do it, it begins in the mind.” https://www.aetv.com/real-crime/jeffrey-dahmer-childhood-serial-killer-cannibal-bones
