People of the bottom begin to look down on Sula because of this. The next incident that occurs is, Sula sleeps with Nel's husband , ending their friendship. Resident of the bottom , now begin to view Sula as evil. Her evil is traced by the plague of robins, sending her grandmother to a nursing home, watching her mother burn, and sleeping with Nel's husband. Nel feels the same way about Sula as the townspeople. After the dispute, Nel visits Sula while she was sick in 1940. Sula does not apologize, and no regrets. Sula even goes as far as to suggest that Nel does not know good from evil. That she is right , and that Nel is the wrong one for abandoning her best friend. Soon after Nel leaves, Sula dies. Sula's last thoughts before dying is to tell Nel that death does not hurt.

Twenty five years after Sulas death , the community changed drastically. Blacks now lived in the valley and whites in the "bottom". Nel goes to visit Eva in the nursing home, and Eva cannot distinguish between Nel , and Sula. She calls them the " same person " . Nel then begins to realize how close her and Sula were. She begins to wonder if Sula was really evil, or just misunderstood.
The main theme in the story is good vs. evil. Sula, although she is a social outcast, she is the heroine of the story (Rhodes 59). Morrison was trying to express that " evil is as useful as good is" (Rhodes 56). Morrison states that evil is not an alien force, but a different force (Otten 28). Sula was seen as evil, but she lived a peaceful life.
