It's human to want to simplify a complicated situation. It's human to want to believe that people who are more ethical, or more attractive, must be more talented. From where I'm sitting, these are completely disconnected variables. (If there are studies correlating them, I'm unaware of them.) But when an artist people like turns out to be a bad person, it seems like it's easier to decide their art was bad all along than to accept the broader idea that terrible people can make excellent art.
