Perhaps the best example of Scout benefiting others comes at the end of To Kill a Mockingbird. After the attack by Bob Ewell and his death at the hands of Boo Radley, Sheriff Tate has a decision to make: Should he tell the truth and begin an investigation (which will implicate Boo and bring him into the "limelight")? Or should he simply call Bob's death one of self-infliction? Tate humanely chooses the second option, and Scout agrees with it. She tells Atticus that investigating Boo would
"... be sort of like shootin' a mockingbird, wouldn't it?"
Scout then escorts Boo back to his front porch, where she sees him safely inside. She takes a long look over her neighborhood, pretending to see things throught Boo's eyes, standing in his shoes. In doing so, she better understands Boo and his mysterious conduct.
The other obvious example of Scout's benefit to others comes when she intervenes between Atticus and the lynch mob at the jail. Things look bad for Tom (and possibly Atticus) until her innocent conversation with Mr. Cunningham humbles the men, who decide to abandon their murderous mission. Scout's intervention saves Tom's life and keeps her father from taking a beating at the hands of the men.
