Explain Scout's growing up?

First off, Scout is a girl. Over the course of the novel, we see Scout mature. In the beginning, she's innocent. Boo Radley is a mystery and a game. Soon, she begins to see Boo Radley as a victim rather than the monster of childhood imagination. She realizes that their games tormented a troubled man. She no longer has interest in "finding out" about Boo. Violent events and threats against her family make Boo seems rather "tame". Scout's current affairs lesson in school turns into a lesson on Hitler, Jews and anti-Semitism. Scout is curious that although Miss. Gates loathed Hitler and his persecution of Jews, she had said, “it’s time somebody taught them a lesson” about Tom Robinson. Scout wonders why her charity didn't extend to persecuted people in her own community.Atticus gently leads her in this direction and Scout discovers the discrepancy herself.
