To be clear, it doesn't bother me if the authors themselves are liberals, as long as the book/story doesn't have woke nonsense. In that sense, I guess older novels would be the best bet.
EDIT - Holy moly, thanks for all of the suggestions. I have my work cut out for me, looking into all these authors this summer.
The Collector by John Fowles, is an amazing look at what is probably a budding killer (ironically, it directly inspired 3 separate serial killers, 2 of which based their crimes directly on it) as he meanders pathetically through life. Unlike most murderer type books, Clegg is an utterly pathetic man who is so beta he cannot even fathom social functioning. So instead he kidnaps a girl to hopefully "convince her to love him."
Which makes it so horrifying is that despite his sad, weak willed nature, he is still able to commit atrocities in pursuit of something almost beautiful. There are dozens of erotic romance novels with the same premise, but instead of Clegg its an alpha chad so its so hot, but because its him its got this layer of creep and uncomfortable horror about his every action. Including how easy it is to feel bad for him.
He was also discovered long after his death to have hated Jews, gays, and Muslims if that makes it better for you. I don't think it shows in his work.
