It would be kind of interesting to see if there’s a ratio of evil characters to their actors doing crimes. I mean the most obvious that comes to mind is Kevin spacey. Though it doesn’t seem to be higher rates for celebs that play evil characters vs ones that play lovable good characters. Least most don’t consider Bill Cosby or OJ Simpson to have played particularly evil characters. So I’d say in general money and fame cause an increase in likelyness of being evil, the on screen persona doesn’t seem to be a huge contributing factor.
