The novel as a whole shows us that instead of there being a distinguished good or evil- it is complicated. We are all evil even though we do not show it. In the Stranger case of Jekyll and Hyde, we are shown a different side of all of us, known as the duality of humankind. This is shown by the different characters of Dr. Jekyll- being educated, popular and kind to all that he knows which shows him as the 'goodness' of the novel. However, Mr. Hyde is the complete opposite- he commits evil acts against innocent people such as the murder of Carew in the novel, which means that he is the 'evilness' in the novel. A reason why we may act like this is that of Freud’s Psychodynamic analysis theory where there are three stages- Id, Ego, and Superego.
