need help on writing an essay the prompt is the good or evil in a person's life sometimes grows out of the strengths and weaknesses, the virtues or defects in his or her charcter. How is this true of any character in this novel.

I think you should check out Gradesaver's themes; they will help you immensely in choosing a character and determining the virtues or defects you're looking for. Focus ob the section sub-titled innocence.

Once you've chosen a character, Gradesaver also has complete character analysis available. You can find both links provided below;
