I feel like a lot of people misunderstand the relationship between Verlaine and Chuuya. There's a lot of argument over whether they're biologically brothers or not. That's not the point. The point is how they came into the world and their unnatural birth. Or, at least, how Verlaine perceives it. He sees both him and Chuuya as artificial beings that will never be human no matter how hard they may try, so they may as well stop trying to fit in with these disgusting humans and just find solace in each other. He calls Chuuya his brother because he feels like he's the only one who can truly understand what he's going through. Their "brothership" stems from their shared existence as artificial beings. This is why Chuuya rejects it so violently at first. He doesn't want to be anything like the man who slaughtered his friends. He wants to be human.
Then, throughout the book, Chuuya comes to accept that however he came into this world, naturally or otherwise, he chooses to be human, and that's what it's important. His actions are what make him human. Verlaine learns this, too, but it's already far too late. He, too, had the chance to be human, but he was too focused on the possibility of being inhuman instead of actually trying to be a good person or to accept the care and support of his friend, Rimbaud, and now, he's gone. That is the tragedy of his story. He always had the opportunity to be human, but he threw it away for the sake of anger and hatred.
Only when they have both learned this lesson that Chuuya accepts Verlaine as his brother. Not because they're biologically related or anything, but because they do have this shared experience with one another, and he's here for him. Not because he forgives him for what he did. But because he has an opportunity to be better.
