Stevenson uses Mr. Utterson as the superego to show the moral values and human conscience in society and also to contrast the good and evil sides of a person. In the beginning, Mr. Enfield tells the story of Mr. Hyde running over the girl, Mr. Utterson is obsessed like a detective with finding the truth. When Mr. Utterson and his guest are looking at the two papers that have Dr. Jekyll and Mr. Hyde’s handwriting on them, they find the handwritings are identical. Mr. Utterson says Dr. Jekyll is making fake evidence for the murderer, which is Mr. Hyde. Hyde.
