Then get back at them in a way that doesn't involve raping the girls. Or better yet prove them wrong by using his skills on female monsters and enemy humans, earn their trust through hard work and action and become a useful member of the group. That would've been better storytelling. This is just self-insert fanfiction hentai trash.
That classmate was 1000% right to kick him out. He was a danger to his female classmates, he set out to prove them wrong and low and behold, he did exactly what the upperclassmen said He would do. Honestly this just a self-insert pervert's fantasy to fulfill a harem they wish they have in reality and get back at those who wronged him.
