Trauma doesn't make more trauma ok

So from the samples of the future chaps it seems like Haga was raped by his teacher who praised him as a sub and lorded it over him, so Haga is traumatised by the prospect of being a sub and is actually a Switch. I know there's probably going to be chapters wasted over justifying his actions so he can be salvaged as a side character (and turned to the good side, maybe for the use of blonde dude), but I'm sorry your trauma does NOT justify traumatising someone else. He has literally screwed someone else's entire life, a complete innocent victim, just because he suffered abuse. If anything it should make him more empathetic, but instead he is trying to satisfy himself and regain some of his pathetic self-worth by putting down another sub.
Long story short, I don't care how they try to justify and excuse his actions, fuck Haga and fuck his mother.
