Question for a piece I am writing?

First of all this story is amazing. I was on the edge of my seat just reading the summary! No joke! Also I think it's more likely to abuse a son because he was abused by his father therefore a chain which will hopefully be broken with his son. I also think you should kills the older son and repeat the story with Mr.Krevok's childhood unless the younger son does something different like lashes out at his father refusing to be abused like his brother. I also think if your having trouble picturing the younger sibling as a girl then make it a younger son and I say lose the twins, it might be harder to keep track of all the kids. Good luck with your story!
