I’ve read all of the books I listed. And most of his short stories as well. I don’t think he hated anyone, he just had a very dark perspective in general. The whole world is grotesque, but the antagonists are adults in a majority of his novels. It’s very much in the tradition of Lewis Carrol; children serve to contrast the absurd and cruel aspects of daily life. Industrialization, authoritarianism, violence, poverty; it’s all deconstructed through a child’s lens.
