You can clearly hear someone continually shouting 'enough Ben' but he kept at it. I would imagine that isn't going to go well against him.
Very noble of him if that is the case but as you say the final punch was a step too far if he hadn't already, he does have previous for having a bit of a short fuse.
From someone I know within the game, this isn't the first time Stokes has been pulled up about his "lifestyle choices".
