What insights into Boo Ragley'y character

Boo Radley is a recluse who never emerges from his house. As a young boy, he was in trouble with the police, and his strictly religious and reclusive parents have kept him indoors ever since. A prisoner in his home, he stabbed his father with scissors once, and no one has seen him since. The town has developed a myth that he is an insane monster who wanders around at night peering into people's windows. Throughout the book, he lives with his brother, who is highly controlling. Boo just wants to make a connection with the innocence of children. He ends up becoming Jem and Scout's guardian angel.
