Authors who have done unsavoury/downright terrible things?

I read the article about the author of Where the Crawdads Sing being involved in a murder and it made me question if there are other authors who have been involved in bad things. You never seem to hear about authors in the way you do other famous people. I would also like to avoid giving my money to authors that have done terrible things.

Edit: I'm sorry I didn't realise this got posted a lot, I've never seen the question before and it seemed topical. Also I do realise that bad people can create beautiful things, I just don't want to give them my money. I like supporting authors by buying their work and I want to know who to not do that for.
