What was the most important moment in A Doll’s House?

I think the most important part of the story is when Nora finally tells Torvald how she has been treated. She tells him that she is just another child to him and she has no identity for herself.

I have been performing tricks for you, Torvald. That’s how I’ve survived. You wanted it like that. You and Papa have done me a great wrong. It’s because of you I’ve made nothing of my life.
