Explaining the four factors that lead to Violent Behavior as learned from my education and direct inmate contact. While these four factors may not appear in every single case in the large majority of cases that I have studied these factors do exist. Much of the direct correspondence I have had with inmates has allowed me to gather information that I would not have known otherwise. It is for this reason that I think it is important that we understand what major factors are the precipitators to violence in serial killers and murderers.
