Duran definitely wasn't a sociopath. The guy wore his heart on his sleeve and let all his emotions out.....which was mostly anger when leading up to fights. You just have to look at that picture of him holding Esteban Dejeus on his death bed to see that he was a compassionate human being.
Back to my nominee, Panchito Bojado. Panchito was charming and good in interviews. By accounts I've heard, he thought he was a big star and tended to act like a jerk. He never really trained well, though, and fell off. Then he resurfaced with that bizarre incident where cops chased him and he tried to plow through the SD/Tijuana border over pretty minor stuff. These things fall in line pretty well with him being a sociopath. Edit: he's out of jail and starting to train again.

Rap sheets aren't proof that someone is a sociopath, but they are a nice place to start. Carlos Monzon: murdered his wife Edwin Valero: murdered his wife Billy Papke: murdered his wife Don King: murdered two people, though the first was ruled self-defense Ron Lyle: murdered a man in a gang fight James Butler: murdered his friend and burned down his house Jo El Scott: murder, **** Esteban De Jesus: murder Curtis Sheppard: murder, **** Kid McCoy: murder, robbery, took hostages, shot a guy in the leg Clifford Etienne: attempted murder, armed robbery, car jacking, kidnapping Paul Spadafora: shot his pregnant fiance in the stomach Leif Larsen: pedophile Dave Hilton Jr.: chid molester Jake LaMotta: raped a friend's wife, attempted murder, pimping an underage girl, robbery, assault Mike Tyson: ****, assault Ike Ibeabuchi: serial ****** Tony Ayala Jr: serial ****** Trevor Berbick: ****** Bernard Hopkins: armed robbery Sonny Liston: armed robbery James Kirkland: armed robbery Dwight Qawi: armed robbery James Scott: robbery Hector Camacho Sr. burglery, beat his children Floyd Mayweather Sr: drug trafficking Michael Nunn: drug trafficking Chuck Wepner: drug trafficking Ray Robinson: beat his wife and children Floyd Mayweather Jr.: beat his baby mama and other women, assault Dereck Chisora: beat his girlfriend,brawled with David Haye Roger Mayweather: domestic violence Michael Dokes: domestic violence Riddick Bowe: domestic violence Diego Corrales: wife beater
Roberto Duran was vicious in the ring, nowhere else. Anti-social personality is a better diagnosis for many criminals in jail in general.
OK Duran and Tyson are almost certainly not sociopaths. They simply dont fit the profile on any level. Don King would be a pretty good call.
