http://www.youtube.com/watch?v=BI3D7h5yxOs when i think sadistic, i think of someone who has no respect for the rules or the safety of his opponent what so ever. I have seen some ****ed up **** throughout time, and some 'HOLY ****! DID HE JUST DO THAT?!' moments, but this ******* took the cake. James Butler would later go on to murder Max Kellerman's brother, who was more or less taking care of the disgruntled fighter. Just goes to show that this lack of sportsmanship was just a mirror reflection of the cunning and sadistic mindset that lurked beneath his skin. He's lucky he didn't permanently injure Grant, a blind sided punch like that can kill a guy.
Anyone who says this as their opponent is being carried out of the ring unconcious; "I had an off night, next time he'll be going to the morgue" is clearly a man who loves to inflict pain and suffering on people. So Duran is my pick.
what about Maxie Rosenbloom he seriously loved dishing out pain look at his Ko record its astonishing nah my real pick is Butler as he is a piece of **** but hes not sadistic as a figther he is just a **** as a fighter i would say Duran was a cold hearted ***** in that ropes what about Ivan Drago if he dies he dies
