"Who are they?” "Jekyll, for instance,” said the lawyer. "He never told you,” cried Mr. Hyde, with a flush of anger. "I did not think you would have lied.” "Come,” said Mr. Utterson, "that is not fitting language.” The other snarled aloud into a savage laugh; and the next moment, with extraordinary quickness, he had unlocked the door and disappeared into the house. Which statement best describes how Mr. Hyde is characterized in the excerpt?
