Compare and Contrast two major characters in the novel Oliver Twist

Oliver is a young, good-hearted, and kind--but often mistreated--orphan who is raised in a workhouse, and finds himself indentured to an undertaker, living with thieves, and eventually taken in by the kind Mr. Brownlow and Mrs. Maylie. His generosity of spirit is total, and even when faced with serious maltreatment, he never loses his sense of morality or kindness.

Fagin is a very old man, with a villainous-looking and repulsive face, Fagin is the leader of a gang of boy thieves, and a very greedy and vicious man. It is Fagin who tries to turn Oliver into a thief, and who betrays Nancy to Sikes, leading to her death. Although the two live a life of the underclass and relative poverty, they are quite different in personality. It is the child Oliver who has a clear sense of right and wrong and the old man who has abandoned such views on morality.
