Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde has several lessons. One moral or lesson is that every person has both good and evil in them. This is the most compelling moral as it is the main focus of the story. Dr.
Jekyll acknowledges that duality exists in people in his statement of the case. He was so interested in this that he started to test separating his evil personality from his good. Dr.Jekyll’s evil side is named Mr. Hyde, who obtains pleasure by committing evil.
Through his experiment, Jekyll discovers that the evil aspect of a person has more of a chance to take over if that person has no good in them. Eventually, Mr. Hyde takes full control of Henry destroying what good he had left.
Another moral of the story is that addiction can lead to a person’s downfall. This plays a significant role in Dr. Jekyll’s life. In the story, he starts to take chemicals to separate his duality, but he eventually begins to over excessively take them.
His dependency on chemicals leads to his ruin as he now depends on the chemicals, and Mr. Hyde has gradually taken over.
