What are the similarities between Sula Peace (Book: Sula) and Pecola Breedlove (Book: The Bluest Eye)?

The major similarity between Sula Peace from
Sula and Pecola Breedlove from The Bluest Eye
is that they are both outcasts in their communities.  Sula does not follow the rules of
the Bottom, and she breaks many social conventions in her relationships with others. 
For example, Sula sleeps with her best friend Nel's husband Jude, and Sula does not
understand why Nel is so angry with her afterward.  Other members of the Bottom consider
Sula wild and brand her as an outcast.  Similarly, Pecola is an outcast in her community
because she comes from a family that is known for violence and abuse.  Pecola goes to
live with the MacTeer's after she is raped by her father, and everyone in town (except
the local prostitutes) looks down on Pecola.  She is seen as ugly by those around her
and she internalizes these views of herself.  Thus, she, like Sula, is an outcast in her
community.
