The art SHOULD be separated from the artist.
Take a look at this drawing:
Beautiful, right?
It is.
But it was drawn by Adolf Hitler.
Just because someone was a rotten human being doesn't mean we should burn their art.
We shouldn't take a page from Hitler himself and ban people from appreciating a work of art. Need I remind you Hitler destroyed hundreds of thousands of works of art because he disagreed with the politics/race/actions of the people who drew them?
The same goes for movies and TV made by bad people. Think about the Cosby Show for example. Bill Cosby wasn't the only person who acted in the Cosby Show. Should Theo's acting and contributions to the entertainment world not be honored because of actions by another person that he had no part in?
