I keep seeing this suggested, and it's really unnecessary. He's a career politician, willing to join Donald Trump to further his ambitions. He has always gone with the team position, no matter how horrific, because that makes him a good team player. He's in it for himself and his own goals, and he doesn't need outside influence to be an awful, weak, immoral person.
UPDATE: To be clear, this isn't a shot at you, Pez. I'm saying the idea is unnecessary, as Pence has shown who he is through all of this.
