At the beginning of the story he mentioned in the game he plays that you have to do anything required to gain power. he never spoke of hate. he only hated the bullies and Other students that wouldn’t help him. Plus We are barely into the story, he might end up hating humanity as a whole. that still doesnt mean he would hate every human, there are always exceptions

I don’t think he hate humans. I think i hates a specific type of human. in his old world, bullies/jocks. in his new world, adventures. though even then he didn’t enjoy killing the wizard girl. plus, which of us Nerdy loners doesnt hope For some attention for A beautiful girl or two?
