Okay the mom (grandma) is beyond the worst. At the very least I can justify the brother/uncle's actions (he was young, had a terrible condition, and was raised by a horrible mother) and he had the decency to grow as a person and accept he was wrong, but god; that mom is just completely horrendous. She was a terrible mother to her daughter when she was alive (and her son really in that she raised him so irresponsibly) and then pushed all the blame on her husband who actually gave her freedom and is now pushing her blame on her young grandson. And on top of this she still tries to play the victim card and straight up stabbed her son in law IN FRONT OF THE GRANDSON (how he handled that as a parent was BTW amazing. As a person he should REALLY stop that bleeding. Like, now). Even if he grows a concience I don't think I can not hate her. I'd much rather she drop dead. I think the author succeeded too well in making her hateful.
