The End is the section where the character now shows whether or not she truly understands her flaw and her part in what is not working in her life.
The Climax occurs at nearly the end of the story when the protagonist commits to helping a woman with a child of her own and two orphans she has taken in. Up until this act, the protagonist has been completely self-centered. She has obsessed about her life and flaws and worries.
At the Climax, we see that the wake-up call that came at the Crisis has ripened into the new personality deeply enough that she is able to extend herself in generosity and help another person. This action is the perfect metaphor to show character transformation. We have a definite sense that the protagonist would not have been capable of doing what she does for this family if she had not experienced every single thing she has undergone previously - the definition of the Climax.
