how does changes in jem and scout affect to kill the mockingbird

Both Scout and Jem lose a certain amount of innocence. Scout discovers that childhood ends, her brother grows up to discover people can let their hatred and ignorance prevail over common sense. Certainly Jem is learning what it takes to become a young man. Much of what both kids learn comes directly from Atticus. They learn not to judge others without walking a mile in their shoes and they experience this lesson first hand (Boo Radley, Mrs. Dubose). Both kids seem to mature in a fashion that reflects their father more and more. That is a good thing.
