Word. This isn't an "the Italian Job" type situation, nor did she ACTUALLY steal any of his money. She won it in a game show, she just outsmarted him from the sound of it, beat him at his own game. Good for her.
Not sure what I would do. She's already been owned in this show, so she played her cards to win this time instead of trusting the guy. You have to size up your opponents and play the mind game.
I would have done the exact same thing as she did. Fuck the haters. You go on a game show to win, not to make new friends and split the money with a random stranger. She seemed so embarrassed that she fucked him over when she really should have been laughing in his face for being such a dumbass.
It's a simple prisoner's dilemma. Given a completely clean scenario, without any outside factors (like actually caring about your reputation) the rational choice is to steal.
Steal for sure anyone who doesn't would be too nice/stupid.
1. You can't trust anyone.2. If you split, you either get half, or get nothing. If you steal, you either get it all, or get nothing.
