I’ve seen people talk about actors and artists that had a terrible time.
My own would be Anne Rice. She wrote Interview with the Vampire after her young daughter died of Leukemia. Then her husband suddenly died of a brain hemorrhage. I suspect her Christian, anti-fanfic phase was a result of mental illness and manipulation from the publishers, although I don’t think she ever apologized.
I don’t feel bad for people who willfully choose hate. I also don’t think he was ever compassionate, he’s a person who chooses to be a part of a particular religion and his writing mirrors the public face of that religion over the decades.
