The more interesting question is: what do we do with the art of people who were revealed to be terrible? I first saw people wrestle with this idea for Michael Jackson and recently it has been a big issue related to Kanye West.
I'm mostly out of that environment now, but occasionally put myself in those shoes again and think how odd it would seem to me that people look up to and expect moral righteousness from these people.
I do expect him not to rape, murder, commit fraud, and so on.
One of the things I occasionally notice about conversations in this area is that some people care more about actions that hurt people than property.
If our hyopthetical rockstar trashes a hotel room, wrecks his car and then has a heart attack from cocaine, that might be judged differently than one that joins the local nazi party and attempts to murder someone.
…I’d assume that would be judged differently than an attempted murder and trashing a hotel room.
The question is what would be the judgement for all three?
Shouting "black lives matter" at a protest is a fairly minor virtuous action. Throwing a rock at a police car is a pretty minor sin.
Attempted murder is generally a pretty major sin, modulo quibbles about legal vs moral definitions of murder.
