In To Kill a Mockingbird, Maudie Atkinson is (like Atticus) a voice of reason, justice, and integrity. It is Maudie who echoes Atticus' sentiment that it is a sin to kill a mockingbird.
Mockingbirds don’t do one thing but make music for us to enjoy. They don’t eat up people’s gardens, don’t nest in corncribs, they don’t do one thing but sing their hearts out for us.
Miss Maudie never talks down to the children. She challenges the superficial hypocrites of Aunt Alexandra's missionary circle. Miss Maudie is also unbelievably optimistic. When her house burns, she claims that this will give her the opportunity to build a smaller house and have more yard room for her azaleas. Miss Maudie is also generous and selfless. Even though her house has burned down, Miss Maudie is only outwardly concerned with the children, Mr. Avery's condition, and the possible commotion the fire caused her neighbors. Like Atticus, Miss Maudie is a fine role model for the children because she teaches them how to act by her own example.
