I see you assume op is a normal person. There’s a history of posts on this and other accounts (some deleted) that indicate op is a sociopath. They have said repeatedly they care about nobody but themself and maybe a romantic partner. They find it unthinkable to care about anyone else in your family. They have said they’ll celebrate children dying because of how little They care about anyone. Even in the context of this post, they’re not only expressing indifference, they’re trying to get a reaction by saying at the end they’d be happy if their parents died, even when the parents clearly did nothing to them, they just don’t care about others. They said non-abusive to make sure we know the parents are innocent, they haven’t been mistreated or they’d say so in the post, they just don’t see why they should care about others. They’re baffled that it’s wrong not to care about people in your family. They’re baffled that it’s wrong to be indifferent towards people who aren’t your romantic partner
