                                                No you’re right. He went through a horrible time, but it’s right to say he’s also now a horrible person. He was selfish, and had an unfair expectation of his sister. Literally told her to go die and then treats her as some kind of monster because she reacted. And then blamed HER despite her going to college and supported herself because her aunt couldn’t 
I do feel sorry for him, but his whole viewpoint of his sister is so shitty it’s sad. I think even if he opened up to her it wouldn’t change, he wants someone to blame and she’s his target                                            

		
I would like to preface that I know the brother's a kid and he isn't out with a master plan and he's just hurt. It's not justified but it's understandable.
I don't think the brother is wrong to hold out his anger over what happened but I do think he majorly oversteps the bounds. He hates his sister but stays in her house, wants her money, rejects all social bids from her, and actively defames her to others.
He's a bully. That's what it is, it just doesn't look that way. Whatever is done to him at school he does to her and he knows he'll get away with it because she's a doormat and she feels guilty over what she did. In my eyes, he doesn't actually care about getting hit per se, he just likes that 1, his pain is validated through her guilt and 2, he has power over someone.
I hope someone gives him some kind of reality check and he stops getting bullied just so he can begin to heal his relationship with the MC. However with how the story is playing out I think (and I severely hope I'm wrong) the lawyer's gonna kill the cousin and frame the kid by posting the photos online and framing the kid as the obvious suspect. My guess is he'll do this because the kid is "dimming" the MC's radiance like the other people so far.
I hope I'm wrong, I HOPE I'M WRONGヽ(`Д´)ノ
