Jem and Scout Finch's views of Boo Radly change during the book "To Kill a Mockingbird" by Harper Lee from mysterious and frightening to friendly and understanding. According to Dramatica's analysis of the book, the children change when they realize that Radley has saved their lives; they finally understand his perspective and accept that he is a good person.
As Jem and Scout witness the trial of wrongly accused Tom Robinson in their racially charged home of Maycomb County, they gradually gain a mature awareness of morality and injustice. Dramatica explains that they begin to realize their own prejudices against Radley and learn to put themselves in his shoes and begin respecting his differences.
According to Book Rags, Jem and Scout learn from their father, Atticus Finch, to be courageous, kind, responsible and to do what is right. Although the reclusive Radley seems mysterious and possibly dangerous, when he exposes and endangers himself to save the children, they recognize these same strong morals in him. They understand that they have misjudged Radley, just as the people of Maycomb have misjudged Robinson. All the time that Jem and Scout are leery of him, Radley is in fact benevolent and protective toward the children.
