I have always wondered what goes through a person's head as they are murdering an innocent human being? Does it register through their heads that they just took someone's life, and that they're going to prison? It's hard for me to even imagine what the person is thinking as they are about to die as well. Criminals being so malevolent and wishing people dead, is sad. Some people aren't even criminals yet, until they have murdered or broken the law first. Why do people do it? Is it in human nature?
