how do you evaluate Chillingworth's and Dimmesdale's character in the scarlet letter?

Chillingworth arrives in Boston on the day that Hester is publicly shamed and forced to wear the scarlet letter. He vows revenge on the father of Pearl, and he soon moves in with Arthur Dimmesdale, who Chillingworth knows has committed adultery with his wife. His revenge is frustrated at the end of the novel, when Dimmesdale reveals that he is Pearl's father before dying. Chillingworth, having lost the object of his hatred, dies soon thereafter.

Arthur Dimmesdale is a respected minister in Boston and the father of Pearl. While Hester waited for her husband to arrive from Amsterdam, she met Dimmesdale and had an adulterous affair with him, which led to the birth of their daughter. While Hester is publicly shamed for the adultery, Dimmesdale must suffer the ignominy quietly since no one knows of his culpability. The suffering begins to take its physical toll, especially since Hester's husband Chillingworth seeks to destroy Dimmesdale and is a constant reminder of the guilt and shame he harbors from his affair with Hester. At the very end of the novel, Dimmesdale admits to being Pearl's father and reveals that he has a scarlet letter branded into his flesh. He dies upon the scaffold while holding Hester's hand.
