And next moment, with ape-like fury, he was trampling his victim under foot and hailing down a storm of blows, under which the bones were audibly shattered and the body jumped on the roadway (60).
Once again Hyde acts in a vicious manner that shocks the maid to the degree that it makes her faint. This impulsive nature that Hyde expresses is the exact personification of the id because it is very instinctual and has no regard for the rational.
Mr. Utterson, a bona fide Victorian gentleman who shows interest in man's dark side despite principles set by Victorian society, is the embodiment of the ego. In "The Story of the Door," Mr. Utterson's obsession with the dark side is first introduced to the reader in a brief description of his character. "But he had an approved tolerance for other; sometimes wondering, almost with envy, at the high pressure of spirits involved in their misdeeds; and in any extremity inclined to help rather than to reprove"(p. 37). In Victorian society it was frowned upon to associate with people commit "misdeeds," but Mr. Utterson does not regard this label set by society with no worry about what it could do to his reputation, which was an important standard set for social classes in this society. When Mr. Enfield tells Utterson the story of Hyde paying the trampled girl's family with a check signed by Dr. Jekyll, he and Utterson are in disbelief. Enfield says, "Blackmail, I suppose; an honest man paying through the nose for some of the capers of his youth. Black Mail House is what I call the place with the door, in consequence"(p. 42). Although Utterson sometimes shows a flexible with his thoughts regarding the other side of man, he recoils back to the closed-mindedness of Victorian society at times, which is why he and Enfield automatically come to the conclusion of blackmail. Mr. Utterson can be open to possibilities at some times, but can also be limited in his thinking at others, which is why he is the quintessence of the ego.
