How does Dr. Jekyll interpret his realationship with Mr. Hyde in The Strange Case of Dr. Jekyll and Mr. Hyde?
In Chapter 10 of The Strange Case of Dr. Jekyll and Mr. Hyde, Dr. Jekyll speaks about his relationship with Mr. Hyde. The relationship is a complex and progressive one. His scientific medical studies were "wholly towards the mystic and the transcendental" for the purpose of answering the questions of whether the two sides of human duality--good and evil--could be separated so that evil could go it's own way without conscience and good could go its own way without temptation toward evil.
In the beginning of his experiments, Jekyll was amused by the ability to shed the respectable life of Henry Jekyll and assume the depraved life of Edward Hyde: "I smiled at the notion...it seemed...houmorous." In the end, after the murder of Sir Danvers and the beginning of Jekyll's spontaneous transformations into Hyde--the first of which occurred on a park bench--Jekyll became repulsed by Hyde, like everyone else was, and hated him with a deep loathing just as Hyde now hated Jekyll.
In Jekyll's confession written to Mr. Utterson he says he can no longer call Hyde "I" as Hyde is "another than myself." Jekyll recognizes the impossibility of a split duality and acknowledges that the creature Hyde is not himself. Jekyll knows that, since the chemical powders are all used up, at the next transformation into Hyde, Jekyll will cease to be and Hyde's destiny will be (he believes) morally separate--if not physically separate--from his own.
