You're assuming TDO knows thing he doesn't and trusts the other gods. He believes he can survive to the next world, so if they take away the card he wants to play, he wouldn't just fold, he would play the other card - try to destroy the world so that he can have a hand in building the next one. He has trust issues already, being betrayed by the other gods in collusion with his high priest would do nothing but exacerbate that, well-known trope or not (and I don't that trope has the powerful person aware of his right-hand man's actions at all times). Further, given that "destroy the world" is already plan B, it seems just a tad more likely than "go dull about it peacefully".
