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.
… Eh, the dude was a dick bag to his wife. I guess he unintentionally went against what his book was meant to be about, which was greedy rich people.
I’m convinced his book was self reflective and self loathing. I think he hated how badly he wanted to be rich and well liked/connected.
