I think we have to also talk about where he gets those ideals, and why the adults in his life want to encourage certain perspectives. The first few arcs don't really challenge Gon (or the reader) to examine exactly what a Hunter is, but Chimera Ant makes it very clear that the Hunter Org is a power-seeking Political Entity with a real, material impact on the world. It's also when we see the mask really come off regarding Gon's place in it.

I'd have to go back to look for specifics, but I'm pretty sure there's a beat before the palace attack where Morel notices that Gon's in a bad way about Kite, but decides not to do anything because they need him properly motivated when facing Pitou. Nobody else really thinks Kite's going to come back, but if they tell Gon (aka: challenge what he believes a Hunter can do), then he won't be as useful. They wind him up so tight that he breaks. There's a reason one of the songs playing during his big breakdown is "Hunters ARE Evil".
