Tell him "Dave, don't be an asshole" and then continue the campaign normally.

You let him roll for attack, pretend to roll behind the screen and tell him that the captain defended himself successfully. His character gets attack and imprisoned. Reroll for new character.

If he genuinely wants to do that, don't let him play in your game. Don't indulge shitters.

Either of these would have worked. Either "You don't do that" or "lol, you shouldn't have done that" would have been stupendous.

You did the right thing, but if they're people who you share any sort of mutual respect with >>54046414 could also work

>I know I'm supposed to respect player agency and all

That's your first error.

Player agency is good, but it works only as long as they're capable of agreeing what the game should be about. If others unanimously agree that one player's action was retarded, it's safe to retcon it for the good of the game.
