Doubles become opposites and demons rather than guardian angels. This is particularly true in inhibited or self-restrained modern societies. Also the role of `good` and `evil` in a person is generally balanced, and In Dr. Jekyll and Mr. Hyde, Hyde thus becomes Jekyll demonic, monstrous self. Certainly Stevenson presents him as such from the outset. Hissing as he speaks, Hyde has "a kind of black sneering coolness . . . like Satan”.
Furthermore the hissing is a function of a snake, and as snakes are seen as evil and devious animals also because of Adam and eve, and temptation it fits the perfect description for Mr Hyde. Also Hyde represents the evil side of Jekyll dual personality, and Jekyll is the good side, and Hyde is known through He also strikes those who witness him as being deformed -- "colourless and dwarfish" and simian like. He is both monster and shadows another self not only for Jekyll but for all the I assume upright Victorian bachelors of the story who recognize his deformity and for who he becomes both mischievous sprite and deaths knell.
The Strange Cafe unfolds with the search by these men to uncover the secret of Hyde. As the narrator/lawyer, Utterson, says, "If he be Mr. Hyde . . . I shall be Mr. Seek" and so will they all. Utterson begins his quest with a rapid search for his own demons. Fearing for Jekyll because the good doctor has so strangely altered his will in favour of Hyde, Utterson examines his own conscience, "and the lawyer, scared by the thought, brooded a while in his own past, groping in all the corners of memory, lest by chance some Jack-in-the-Box of an old evil should leap to light there" .Like so many famous Victorians, Utterson lives a mildly double life and feels mildly apprehensive about it.
A repulsive dwarf like Hyde may jump out from his own boxed self, but for him such art unlikely creature is still envisioned as a toy. Although, from the beginning Hyde fills him with distaste for life, not until the final, fatal night, after he storms the cabinet, can Utterson conceive of the enormity of Jekyll second self.
Only then does he realize that "he was looking on the body of a self-destroyer” Jekyll and Hyde are one in death as they must have been in life. out the story as a `juggernaut`(monster),and this represents evil a Poole, Jekyll servant, and Lanyon, his medical collaborator, are even more incredulous. When Poole sees Jekyll/Hyde in his final form, he thinks he sees his master with a "mask" on his face: "that thing was not my master and there's the truth" .Yet again, Poole's "thing" is monkey-like and dwarfish, and it weeps "like a woman or a lost soul" .When Poole and Utterson hear Jekyll on the opposite side of the door that last night, they react like Ralph Nickleby's would-be rescuers.
The voice they hear sounds like something "other," not like the person they know. Lanyon, alas, never survives to that final night. An earlier party to the knowledge that Jekyll and Hyde are one, he has already lost his life to that secret. A man who believes in rationalism and honest morality, Lanyon simply cannot adapt to the truths uncovered in the revelation of Hyde: improbability. He sinks slowly into death, his body following the lead of his "sickened" soul.
His too is a kind of suicide, a death permitted, if not willed. Lanyon simply cannot accommodate...
