How about in the first one at the church when he is being baptized, and the preist asks him, "Micheal, do you renounce satan?"
And he says he does.
"And all his works?"
"I do renounce them."

That was very important because at that time the heards 5 families were being murdered, and its the start of micheals empire, and also the start to his dis-honesty and cold heartedness.
