In the story of Dr. Jekyll and Mr. Hyde the duality of human nature is one of the major themes. The question if people are born good or evil isn’t answered in the text but we are able to see how it could go both ways, and the views of the author on this subject. Stevenson is able to show his readers that humans aren’t born inherently bad or good, but somewhere in the middle. By separating the good, Dr. Jekyll, and the bad, Mr. Hyde, we are able to see that humans have both and one without the other can sometimes be overpowering.
Throughout the novel it is hard to imagine Dr. Jekyll and Mr. Hyde being the same person because of their differences. It is apparent that Mr. Hyde is full evil, but what isn’t as noticeable is that, Dr. Jekyll, who is suppose to be completely good, has these desires which can’t be fulfilled on his own. He knows that everything he feels isn’t right but inherently there is a desire to learn more, and to be curious about these things he’s been told not to do his whole life. This led to the creation of Mr. Hyde and the release of all things evil inside Dr. Jekyll.
This novel is able to explain why good people do bad things. Even the best people want to know how far they can push their boundaries and what they can get away with. The creation of Mr. Hyde was Jekyll’s way of doing this and releasing his inner demons. There is no such thing as an all-good human; Jekyll says at one point “man is not truly one, but truly two.” Meaning that he is fully aware that there are two personalities inside of people, and he learns very quickly after successfully completing his experiment that you need the one to balance out the other.
In Dr. Jekyll’s case there is too much good, he feels responsible for all his actions and he knows exactly what is right and what is wrong. He always does the socially acceptable thing and never strays away from that. With Mr. Hyde it is the opposite, he is filled with bad and does everything wrong. He feels great joy when doing the wrong thing. Eventually the bad starts to take over and this is when Jekyll realizes how wrong his experiment was. He becomes aware that good and bad balance each other out. Being too good isn’t always the best option, without a little bad life gets boring, which is why he wanted to create an alter ego. The same goes for being all bad, there has to be good to balance it out.
