how far does family represent destiny in to kill a mocking bird ?

I suppose we can pick two extremes here. The Ewell family is destined or catastrophe. The family, if you can call it that, is always in a state of sordid poverty and dysfunction. Bob Ewell is the father and is perpetually drunk and unemployed. His relationship with his daughter Mayella is questionable in the most horrid sense imaginable. Their destiny is bleak. Atticus and his family, I include Calpurnia, is progressive, empathetic and bright. Atticus has fostered a very human atmosphere that teaches his kids the very meaning of loyalty, dignity and courage. Their destiny is the polar opposites of the Ewells. The Finch family means hope for the American South and people in general.
