How does the community react to Mrs. Radley's death in To Kill a Mockingbird? How is her death disappointing to Jem and Scout?

At the beginning of Chapter 8, Mrs. Radley dies of natural causes. Scout mentions that her death had a small effect on the community of Maycomb and people hardly noticed. The Radleys were "foot-washing Baptists" who did not socialize with their neighbors like the majority of citizens in Maycomb. Scout says that the only time the neighbors saw Mrs. Radley was when she was watering her cannas. Scout and Jem are upset when Atticus tells them that she died of natural causes. They figured that Boo Radley had finally killed his own mother. At this point in the novel, Jem and Scout are still under the impression that Boo Radley is a violent individual who wreaks havoc throughout the neighborhood and is capable of harming his family members.
