In title of to kill the mockingbird. In this story of innocents destroyed by evil, the “mockingbird” comes to represent the idea of innocence. Thus, to kill a mockingbird is to destroy innocence. A number of characters (Jem, Tom Robinson, Dill, Boo Radley, Mr. Raymond) can be identified as mockingbirds—innocents who have been injured or destroyed through contact with evil. After Tom Robinson is shot, Mr. Underwood compares his death to “the senseless slaughter of songbirds,” and at the end of the book Scout thinks that hurting Boo Radley would be like “shootin’ a mockingbird.” Most important, Miss Maudie explains to Scout: “Mockingbirds don’t do one thing but . . . sing their hearts out for us. That’s why it’s a sin to kill a mockingbird.” That Jem and Scout’s last name is Finch (another type of small bird) indicates that they are particularly vulnerable in the racist world of Maycomb, which often treats the fragile innocence of childhood harshly.
