OJ killed 2 people in a fit of rage. Rae Carruth conspired to kill his pregnant wife. Ray Lewis killed 2 people during a fight at a night club.

Hernandez is a damn serial killer. He executed his friend in cold blood because he couldnt trust him. He shot his friend on the way home from a strip club and the dude lost an eye. He possibly killed 2 people last year after a fight in a club and god knows how many other people he has killed.

Hernandez is easy #1. Sure the other people on the list have killed people but Hernandez is the only true murderer.
