Yeah, I was sad when the old guy "died" in the marble game, but when they showed him alive and revealed him as "the host" in the last episode, it pissed me off. He wanted to play because he wanted to feel like a kid again, but he wasn't subject to the same rules as everybody else. There's no way they would have killed him if he had lost a game. Even during the red light green light and tug of war games, the frontman would have found a way to save him. But everybody else died, and he created the games to see if there was any humanity left in people. It would have been more humane not to kill people that lost a game. What a fucking prick.
