What makes a serial killer a serial killer? Why does he/she do the horrible things they do? In my own opinion, I believe that the reason they do these things is because of their childhood/teen years. The way they were treated and/or taught is how they are going to act in their later life. If the child/teenager was abused, tortured, raped, etc., they are going to be warped and become what is the exact opposite of human. That person will treat others the way that he/she has been treated: horribly.
That is why I think Serial Killers do what they do. What is your opinion??
