How does the author address the theme of change in The Color Purple?

Celie's change or transformation from a young passive girl, who is the object of violence and cruelty from her stepfather and her husband, into an independent woman with self-esteem is at the heart of The Color Purple. While the ways in which conflicts are resolved may stretch the imagination at times, they are central to the author's view that goodness can triumph over evil. That Celie is able to forgive Albert by the end of the story and take him in as a helper reflects Walker's insistence on the redeeming quality of the human heart. She shows in transformed relationships that the worst cruelty committed by one person on another does not prohibit a change of heart. Her view is basically that the conditions under which human beings struggle shape their behavior. Albert had a difficult life and took out his frustrations on Celie. When Celie became self-sufficient, she could easily have turned her back on Albert, but it is not within the framework of her character to be uncharitable. In becoming independent, Celie has found happiness. Rejecting Albert would detract from her happiness. Celie's behavior toward Albert reflects Walker's insistence on forgiveness and contributes to the overall religious overtones of the book.
