Since it's familial love issue, it hurts personally. Specially when it revolves around the thought of "i love him, why couldn't he understand" then proceeds to show favoritism to others. Why couldn't some parents just learn how to express their affections more directly and communicate with their child?
I'm not generalizing and invalidating her or some parent's efforts but... cuz i feel like her redemption to her son would be forced in a way that he couldn't even do something since she's dead. Plus he have an orphanage full of children to take care of really..
Btw don't mind me, this is just the ignorance of a non-reader of the novel speaking
