Boo Radley was a good person but perceived as someone who must be isolated. He himself chose to isolate himself from society. The justice about whether to judge him as a murderer or a defender was overlooked by Atticus because of Radley's history. The instability of Boo's family highlights the theme of how even within homes, equal human rights can be ignored. Aunt Alexandra is traditional and prejudice at first but becomes open to the views of Atticus because of her love for the family.
