Can Bad People Do Good Work

Today at a second-hand bookstall I found a collection of articles by Clement Freud. I bought it and began to read it and so far have found it hilarious. 

The book was published in 2009. In 2016, after Freud's death, two women revealed Freud had molested them when they were in their early teens. One was raped by him. 

Is it wrong to continue to find someone's work hilarious, once they have been revealed to be wicked? It was easy to forego the creative output of Jimmy Savile and Rolf Harris as neither of them ever created anything I was interested in. I think most of Wagner sounds like the score for Ben-Hur so his association with Nazism has never meant I've had to think about depriving myself of his music, as I wouldn't choose to listen to it anyway.

The dilemma comes when one likes the work, but not the person who created it. Caravaggio was a murderer but his Taking of Christ is still marvellous. Bill Cosby's monologues would probably still make me laugh - and Kramer in Seinfeld certainly does.

Does it achieve anything to refuse to be amused by Clement Freud's anecdotes? Is laughing along with what he writes a way of being complicit in his actions?

I suppose there's the whole performance of reading someone's work in the light of ghastly posthumous revelations. That seems to be a tactic for Alice Munro fans. In both instances - Munro and Freud - I rather wish that particular light thrown on their work had remained dimmed
