Ex-MMA star War Machine insists he's no longer the woman-beating maniac he used to be -- he's found Jesus and changed his life ... and he's begging his ex-GF for forgiveness.
War Machine's story made national headlines -- he was a super talented UFC fighter who lost it all in 2014 when he viciously attacked his then-girlfriend, Christy Mack, when he caught her with another man.
Mack's injuries were horrific -- 18 broken bones, broken eye socket, broken nose and a lacerated liver. The other victim, Corey Thomas, was choked out and bitten before escaping.
