I've briefly met guys like this; spec ops guys who are just cold as hell after doing some seriously messed up things. I mean, I'm not one of them, but I've met them.
They were definitely OP compared to everybody else, and they always did what they were told, and they were always very humble.
Probably because they knew their own worth, and didn't have anything to prove; they knew they could kill everyone in the room if they wanted.
Just like the MC, here.
