Identity in Sula

With Sula, we see a woman who had to fight her entire life to get the things that she needed to survive. She eventually even became a prostitute. Sula seems to be searching for herself the entire novel. In the beginning of the book she loses her home. This can be symbolic for an identification with family or traditional values. This is very different from the concept of identity in The Color Purple, because Celie just needed people to help bring out her voice so she could stand up for herself. She had more of a psychological change. Sula has to deal with black politica, social and moral conscience. All these things play a toll on her life. Even when she tries to go back home later in the novel she ends up having relations with Nel’s husband. Nel who merely wanted that life she always dreamed of blames Sula, but at the same time I wonder why Nel’s husband was not able to resist or even to hesitate really before commited adultery.
