I saw a comment about how professor Snape from Harry Potter was just an a glorified incel. That struck me for some reason because there is truth to that. He was obsessed with a woman who didn’t love him and joined a facist ideological group. He redeems himself as we all know but it left me questioning what other books have incel type characters or just involuntary celibate characters in general. I read the sound and the fury and one of the main characters “Quentin” could be viewed as an incel. He was a virgin who was painfully obsessed with his sister losing her virginity and woman having sex before marriage in general. He ends up killing himself.
