This guy has admitted to killing his own cellmate, and normally he would be seen as a murderer without any regard for human life. When you find out why he did it however, you may think differently. He killed his cellmate because he was a child molester. He said that his cellmate used to sit above him and talk about what he had done, and how he justified it.
This one will send chills right down your spine, because the way he tells his story is both disturbing and harrowing. Watch this video and see for yourself, he shows no remorse, and he even describes in detail how he killed him in front of the judge. It is obvious that he is proud of it; however this can be seen from many different perspectives.
