Yeah, and both those books have deliberately hopeless endings -- Winston Smith is defeated, and IIRC at the end of Flies the boy (Ralph?) knows he can't go back to civilization and be normal, and in fact civilization itself is built on a lie. I agree Camus is way different -- I think because of his existentialism, which is kind of like Beckett's "I can't go on, I will go on." If the people are hopelessly broken and no resistance is possible, that's grimdark for me.
