Compare guilt and innocence based on the conclusion of A Christmas Carol.
This is above all else a story of redemption. Scrooge is redeemed when he is forced to take a moral inventory and realizes that he is severely lacking. Scrooge's sins are greed and selfishness. He cares only for gathering money for money's sake. Note that he does not spend it. By contrast, the innocent characters in the book like Bob Cratchit and Tiny Tim, Fred and Belle care for others first and foremost. They do not have much money, but if they do get money they spend it on the ones they love.
