describe the contrast between chillingworth demeanor and his inner feelings, also report the effect he has on dimmesdale

Chillingworth, having figured out that Mr. Dimmesdale is the true father of Pearl, goes on a subtle campaign to hurt the minister as much as possible. Revenge consumes him to the point that he can only focus on causing the other man pain. Dimmesdale never figures out that his strongest enemy is the man whom he considers his only friend and physician. Chilingworth now has a passion to destroy the father of pearl. Dimmesdale also has become a masochist, and he uses chains and whips to beat himself in his closet. In addition he undertakes extremely long fasts, refusing to eat or drink as penance. This fasting causes him to have hallucinations in which he sees his parents, friends, and even Pearl and Hester. One night he decides that there might be a way for him to overcome his anguish, and he softly leaves his house.
