Will Smith goes on stage at the Oscars and hits Chris Rock then verbally threatens him from his seat

My comparison was based on both being people whose work I previously liked and now don't like because of what they did; Smith for slapping Rock and Kelly for raping teenagers. I never attempted to compare their crimes or say that one crime was equal to the other crime. It's an apt comparison in my view. My level of disdain for both is not contingent on the heinousness of the crime.
I understand what you are saying and I dislike them both as well. But, Will Smith has a path to redemption for me while R Kelly has a path to hell only. The interview Will gave with Trevor was a good one, especially when he mentioned the child asking "why". It's a good watch.
