"Okay, I'll rephrase. Is it worth tarnishing the faith MK has in us permanently even though yeah, he'd forgive us?"

He's really not down to split hairs over that, or the fact a threat and actually doing aren't the same thing. He leans on the wall, waiting for Macaque to finish scouting and looking at a random poster in a window.

He's not likely to rat them out if they go overboard or get creative, but he's not going to be joining in. MK's faith in him means more to him than his immortality. More than his life if he was mortal. That's what he's about.
