I'd like to point out to everyone calling her brother a scumbag, even though I agree and he is dirty and disgusting, let's not forget he was a child just like her, trying to protect her from his so called father who raised him to be the scumbag we see him as and what he's interpreted as, he's a victim as much as she is. He has learned that through abuse is the only way to get the answer he wants which was what happened to him through his father, and he's learned the only way for her to survive and stay in their "safe" environment is to continue marrying her off and getting her back as always, he truly thinks that's the only way to guarantee her safety and keep her from leaving him.
