"I told Wilhelmina I would have to speak to her parents about..." — Ted Chiang quote meaning

I told Wilhelmina I would have to speak to her parents about what she had done. She seemed unconcerned. “I won’t apologize for bringing people closer to God. I know I’ve broken rules in doing so, but it’s the rules that need to be changed, not my behavior.” I told her that people couldn’t simply disobey rules just because they disagreed with them, because society would cease to function if everyone did that. “Don’t be silly,” she said. “You lied when you sent that mailgram as Mr. Dahl. Was that because you believe we should all be free to lie? Of course not. You thought about the situation and concluded that lying was justified. You’re prepared to take responsibility for what you did, aren’t you? Well, so am I. That’s what society needs us to do, not to follow rules without thinking.
