@ntxhiav I understand where you're coming from, my gut reaction when I read this chapter was uh, not that pleasant,
but if we're going from real life standards, I believe that most of the behaviour of him and his sister is due to their environment.
The reason that many children don't go to jail for trying to shoot their sister with a shotgun nowadays is because society goes against it, everyone has almost the same standing and almost noone gets put on a pedestal like they are. I think the reason both of them act the way they do is because of this reason, they're being put above others, and their fathers behavior (curse him) has probably effected them aswell.
At the current I can't quite bring myself to hate them both as you do, as in my eyes they're just children.
Childrens thoughts, emotions and actions are that of an undeveloped brain, many unable to even slightly realize the damage of what they are doing, they oftenly act impulsive on a whim on feelings like jealousy and hatred. It is thanks to our current societies standards that your local neighbourhood doesn't go around with the AK-47 sniping their cousins, because most parents scold their children and teach them what is right and wrong.
It is because of these reasons that people in the real world don't go around calling twelve year olds manipulative little b****es, they cannot comprehend the weight of what they are doing.
I was when I was extremely young, I'd say around six perhaps? Quite the rude little rat child, but I couldn't realize that what I was doing was wrong, I hadn't learned that yet.
Of course, I realize now that I was extremely stupid, but my brain back then couldn't comprehend the weight of my actions. (This is also why children do not go to jail in most countries.)
It's nice to see the viewpoint of someone other than my own though, it feels refreshing.
