Don't express an opinion in a comment section if you're going to crash out because you didn't get validated. And sorry for noticing patterns? Good fiction tells the truth about life in a way a report can't. Noticing these things is part of appreciating a work.
I don't "disagree" or take issue with the OP. OP likes toxic fiction and enjoys reading toxic characters. Not my thing but that's part of what fiction can do, let you explore things you can't (or shouldn't) IRL. I take issue with your insane position that generational torture and murder is cool because a bad thing happened once so that means he's not a bad person.
Trauma cycles are real and that's what makes them terrifying, because it victimizes people and turns them into monsters. The initial trauma in no way mitigates or justifies the subsequent infliction of further trauma on others, and they, very sadly and tragically, turn themselves into monsters through their actions. That's how people actually work.
In this case, Rose wasn't even properly human in the first place, which is another lesson: don't mess with spiritual forces you don't understand it never works out for you. Especially if they want to fuck.

Okay listen I might be biased towards monster/non human men and big red flags but rose is right, even if mc's mom seemed to get better we all know she isn't gonna change because she did it before,
also about the maid, SHE LITREALLY TRIED TO KILL YOU BY PUTTING THE ROSE THERE, rose was doing you a favor by killing her,
Tho rose killing those twin roses as upsetting they didn't deserve it, other than that it's ok king u in the right ong
