You can't just kill the remaining players because depending on which team is fully killed first, the other team would win.
I'm trying to make it so that if the last two players are in a knife duel and neither of them kills the other by the time the round time runs out, I don't want either player to win. I want them both to lose. Ideally I'd end the game on a draw and then smite those two players from upon high, after the draw is registered, for their insolence.
