The punchline is that Hakkai's the biggest asshole of them all.

"Yeah, well..." He's making some good progress on this hunk of meat! Only, what, twenty pounds more to go? There's a lot of food here. "If I do, you're gonna call me out on it, right?"

That's... there's a lot of trust in that statement. More than Gojyo was expecting to express, but having said it, he realizes it's true. He can't put everything on Hakkai -- if he fucks up, he needs everyone to tell him about it. Hakkai, Chikusa, the dog... It's the only way he can be sure that he doesn't make another mistake like that time. He doesn't have so many friends that he can risk them like that again.
