Jekyll as the embodiment of Jekyll's instincts.
In the book, Hyde is presented as the most disgusting and nasty person. As the reader goes on, he expects something even worse to happen. The reader sees how he is rejected. Hyde does not want to listen and does not care about anything or anyone. The audience starts to think that this "supernatural creature" cannot be controlled anymore. But in order to want a personality formation of any kind, there must have been something wrong with Jekyll's past. In the book, in Henry Jekyll's Full Statement of the Case, is mentioned that something was going on when he was a child. The reader must use all the information in the book that he/she already knows in order to understand the importance of why Jekyll wants so much to be a new person. As an adult, he remembers his first recognition of strangeness inside him, followed after a reference to a memory of time spent with his father. .
As when it comes to Hyde, when he is wanted for murder, he causes real problems: " Mr. Hyde had numbered few familiars-even the master of the servant maid had only seen them twice; his family could nowhere be traced; he had never been photographed; and the few who could describe him differed widely, as common observers will. Only on one point were they agreed; and that was the haunting sense of unexpressed deformity with which the fugitive impressed his beholders". .
The very end of the book shows how the life of a good-looking, wealthy, social and good person, on the other hand, ugly, deformed, short criminal, ends because of one more little luxury that he wanted to have. The last night of his life, Mr. Hyde spends in the laboratory, running back and forth all nervous and worried that the police is close by and that he does not have anymore of his white magical powder. Without it, he will become Hyde forever. Hyde was fighting to be free of Jekyll and Jekyll was fighting to be free of Hyde.
