Atticus Finch is a man of strong morals. He follows them exclusively, and does not hold up to the Finch family name, as defined by Aunt Alexandria. Scout finally understand all the things he says. She then realizes that Mrs. Caroline did not know Maycomb, and could not just learn it in one day. Scout comes to terms that it was wrong to become upset with Mrs. Caroline.
Scout learns several other lessons.
Through clarifications from Mrs. Maudie, Scout accepts her father s words. Atticus also teaches his kids a lesson when he defends Tom Robinson, an innocent black person. Although Atticus knew from the instant he accepted the case that Tom had no chance, he had to do his duty as an honest and impartial citizen of Maycomb. Atticus poured his heart into defending Atticus, and did a damn fine job. He taught his kids the right thing, that all individuals are created equal.
