Over the course of the novel, Hester remains unchanged in some areas, such as strength and honesty, but her beauty and social status vary greatly. Somewhere during this period of time, their solace becomes passion and results in the birth of Pearl.
Hester also becomes a kind of compassionate maternal figure as a result of her experiences.
We know very little about Hester prior to her affair with Dimmesdale and her resultant public shaming. His single-minded pursuit of retribution reveals him to be the most malevolent character in the novel.
This piece is truly timeless.
Hawthorne attributes this transformation to her lonely position in the world and her suffering. And in the forest scene, Dimmesdale acknowledges that she has the strength he lacks and he calls on her help in his time of need.
