Since his mentality is all about reducing his actions into a "simplest" form; both dialogue and fighting are well served by trying to break that naive worldview of his. Hunger is well positioned to do it, in this respect; he knows that sacrifice, even of what he held most dear, is not the end; nor is it enough to overturn the systems of a world. If he gives of himself so utterly to achieve his ends, by the end they are just going to snuff him out. It happened to his father, and it will likely happen to his sister too. He is just a pawn to them, useful in the moment but discarded the moment he becomes an inconvenience. If he spends himself, sacrifices himself, he won't be able to protect what he holds most dear. Only by walking away, or by breaking the system, he can have peace.
He can be powerful by committing everything to a single thrust, a linear action, but the world is a far bigger place than that. By single-mindedly pursuing this goal, devoting everything towards that single action, he becomes unable to see the bigger picture. To see the exploitation and tragedy for what it is, and that becoming an Inner Resident won't be the end; far from it. We have to make him see this.
