In The Strange Case of Doctor Jekyll and Mr Hyde by Robert Louis Stevenson a scientist, Doctor Jekyll, creates an alter ego using a draft to escape the harsh opinions of society . As Mr. Hyde, he commits heinous crimes against citizens and becomes addicted to the perception of freedom from Victorian laws. As stated by Norman Kerr regarding addiction, “there is an intoxication-induced imbalance of the mental faculties, so that consciousness, perception, reasoning, power, and consciousness are impaired” (Kerr 138). The character of Dr. Jekyll illustrates the condition of dependency in the Victorian era through the motifs of obsession with appearance and duality. Dr. Jekyll's obsession with appearance causes him to become dependent on the character of Mr. Jekyll himself. Dr. Jekyll is a symbol of both good and evil in humanity, while Mr. Hyde represents pure evil. For example, when Doctor Jekyll is himself, he is seen as a respectable man adored by his colleagues: “he has once again become their familiar pursuit and their entertainer; and while he had always been known for his charitable works, he was now no less distinguished for religion” (Stevenson 29). However, when Dr. Jekyll transforms into Mr. Hyde, his morals are quickly ignored. An example of this occurs when Mr. Hyde kills Sir Danvers, shortly after Dr. Jekyll submits to the temptation to transform himself into Mr. Hyde: "immediately the spirit of hell awoke within me... with a transport of joy , I tore at the body that would not resist, savoring the pleasure of each blow” (Stevenson 56 Although the carnal side of Dr. Jekyll appreciates the incident, this event also illustrates the side of Dr. Jekyll’s conscience because, in the midst of this). brutal murder, he begins to feel guilty for having committed the crime. Guilt drives him to have "folded his hands to God...tears and prayers to drown out the crowd of horrible images and sounds that his memory swarmed against him" (Stevenson 57). Overall, the text demonstrates that Dr. Jekyll's alter ego, Mr. Hyde, is the mastermind of pure malevolence who participates in activities that Dr. Jekyll cannot experience. For example, the appearance Dr. Jekyll's physique begins to deteriorate when he stops taking the potion. The text describes Doctor Jekyll's physical characteristics as "a deathly sick appearance" while his is usually a "large, well-built, smooth-faced man of fifty, with something cunning perhaps, but every mark of ability and kindness ” (Stevenson 19-25). Not only does Dr. Jekyll's health begin to decline, but his behavior changes as well. Normally, when Dr. Jekyll received a visitor, he greeted him with a warm welcome, but as the text in chapter 4 illustrates, Dr. Jekyll did not have the strength to greet Mr. Utterson: “He did not rise to meet his visitor, but he extended a cold hand and welcomed him with a changed voice” (Stevenson 25). Another example of Dr. Jekyll's behavioral change is seen when he physically separates himself from his colleagues for days on end locked in his laboratory, forcing his friends to check on him repeatedly. This act of withdrawal connects to the reality that an addict faces during rehab. The aforementioned addict must isolate himself from temptation to be successful in the recovery phase. The ultimate behavioral change for Dr. Jekyll is shown through his reiteration of cutting all ties with Mr. Hyde and his outburst of violence.
