Conor McGregor
McGregor is the most lucrative MMA fighter in the history of the sport. The UFC maintains one set of rules for the Irishman and another for everybody else. They recognize that he’s a massive cash cow and don’t want to risk offending him because of his marketability.

However, McGregor is also an appalling human and has made a bunch of questionable decisions. The UFC failed to suspend the fighter when he faced sexual assault allegations or multiple arrests for minor offenses. There’s no moral compass when the dollar sign light is on (via NZ Herald).
