Let me give the devil's advocate perspective on this guy. Cain's rise to the top was 50% spent beating up the ghost of Big Nog and a WWE wrestler. Cain's championship run was spent fighting two fighters, Bigfoot and JDS, which while somewhat impressive, let's not forget JDS knocked Cain out in one of their fights.
The moment he fought someone else they knocked him down and strangled him out. One win against Browne (who would never win again) was followed by getting Ngannou'd who mercifully wasn't given the chance by the ref to deliver the ol' Ngannou special (cheapshot).
As for my opinion, he was a super entertaining fighter. Good luck at his upcoming trial, I can't imagine was it would be like to have a child molested by the people you're paying to care for them, that feels like hell on earth. But you can't go around shooting people like that, especially innocent bystanders.
