Wow. Bad father of the year award right here
Even if I know the next chapter they're gonna redeem him somehow, this is no way to speak to a child, especially one with communication problems.
Tough love whatever, you already know your son suffers from a disability, and talking down to him like that wont change anything, you're just gonna turn him bitter and resentful about himself.
Yeah yeah, he's doing it so his son has no regrets on leaving him behind in the forest and living a better life elsewhere, but is that really what he wants? to disassociate from his family and forget they ever existed? There's nothing wrong for him to want to come back home and see his family, I don't understand why casting him out will make him "stronger", that stuff is how resentful and bitter people are made. Yeah they get tougher, but that's because they block the trauma of not feeling love and may eventually do the same to others in the future
