Roger Chillingworth's Transformation.
Roger Chillingworth changes his life forever when he decides to remain in the colony and search for the fellow that betrayed him. He is changed from a person looking to find his wife and be happy to a spiteful person who is consumed with the thought of revenge. Roger has been transformed from one extreme to the other without the conscious thought that this one decision would transform him so completely. Roger's intuition tells him who it is, but he wants to have proof against the culprit.
When he first arrives in the colony he is expecting to find his wife innocent as the day he left her and live a happy life with her. Instead when he reaches the village he finds his wife on a scaffold being punished for adultery. He is furious but quickly masks his anger by sheer will. When Hester refuses to tell Roger who the other adulterer is Roger vows to find out who has betrayed him and seek revenge on this person. When he makes this decision he does not realize he is sacrificing his own sanity and health to find the adulterer. .
Before Roger makes the decision he is best by this quote, "Old Roger Chillingworth, throughout life, had been calm in temperament, kindly, though not of warm affections, but ever, and in all his relations with the world, a pure and upright man" (113; ch.10). Roger was a man with a dream of happiness with his wife in Boston. Roger is a scholar in many things. He is slightly deformed, older than her, but not so that she could never respect him. When he finds out what Hester has done he changes into a man bent on revenge. He is utterly consumed with hatred. He wants nothing else but to find the person who betrayed him and his wife and make them pay for their transgressions.
Roger Chillingworth is transformed from an intelligent man with a dream to a man who would now be unstable. " In whom he hoped to find embodied the warmth and cheerfulness of home," (113;ch.
