Why would you choose steal here, if you actually believed he had precommitted to it? There's a decent enough chance he would honor his word. I doubt you would gain much, if anything, from appearing spiteful on TV.

I'd gain all of the money for a start. You are not going to have much luck convincing me that 'steal' is irrational here given that it has better overall strategic properties (than this guys ploy) and happens to be the winning move in this case.

Choosing 'steal' vs 'steal' doesn't seem particularly spiteful to me.
