And even then, at the very beginning, Aziraphale knows, he KNOWS, that he wasn’t supposed to do give the sword away, that he’ll be in trouble if he gets caught, he’ll even try to lie to God about it. He knew he was doing something of which Heaven would Not Approve but he saw the humans and pitied them and showed them kindness and tHAT WAS HIS REBELLION and Crowley always said he didn’t mean to fall, he just asked questions. Well, Aziraphale didn’t stop to even ask the question, he just did what he thought was right, out of kindness, out of love, so damn RIGHT this is the moment Crowley fell in love because I believe one of the first questions he asked was “why can’t we be kind to each other?” This is why he showed no surprise at the crucifixion. But Aziraphale just went ahead and helped the humans because they were cold and vulnerable and weaker than him, and Crowley saw that and said to himself, “Ah, here. Here at last is someone I can worship.”
