Boo Radley, one of the story’s most notorious “mockingbird” represents the idea of it being “a sin to kill a mockingbird” as all they do is “sing their hearts out for us”, meaning that to hurt something or someone so innocent is a sin because all they do is help others. In the tale, Boo is an innocent person who has done nothing but help Jem and Scout. The writer conveyed to the reader, using little gestures of kindness Boo did, showed the innocence and purity of Boo. However, this innocence was damaged and attacked by his abusive father.
