Major Themes

Good vs. evil

Good vs. evil is basically the novel’s biggest theme. More specifically, Dr. Jekyll and Mr. Hyde is easily viewed as an allegory about the good and evil that exist in all men, and about our struggle with these two sides of the human personality. In this book, then, the battle between good and evil rages within the individual.

Repression

Repression is indisputably a cause of the troubles in Dr. Jekyll and Mr. Hyde. The repression here is that of Victorian England.  Everything is sober and dignified, and you’re really not supposed to be happy. (That would somehow take away from your focus on morality).

Friendship

Friendship in Dr. Jekyll and Mr. Hyde serves to drive the plot forward. Aside from basic curiosity, Mr. Utterson is compelled to uncover the mystery of the evil man because of his friendship with Dr. Jekyll. In this sense, friendship acts as both a motivator and an enabler. differences of opinion.

Appearances

Appearances figure in the novel both figuratively and literally. Dr. Jekyll definitely wants to keep up a façade of respectability, even though he has a lot of unsavory tendencies. In a literal sense, the appearances of buildings in the novel reflect the characters of the inhabitants.

Science

In Dr. Jekyll and Mr. Hyde, Science becomes a cover and justification for supernatural activities. Dr. Jekyll ostensibly derives his potion in some sort of scientific manner, as opposed to finding a magical amulet or something that releases evil as you might find in other stories.

Curiosity

In Dr. Jekyll and Mr. Hyde, Curiosity drives the characters to seek knowledge. This curiosity is either suppressed or fulfilled in each character. Curiosity lacks any negative connotations; instead, characters who do not actively seek to unravel the Jekyll and Hyde mystery may be viewed as passive or weak.

Secrecy and Deception

In Dr. Jekyll and Mr. Hyde, the plot is frequently driven forward by Secrecy and Deception; Mr. Utterson doesn’t know the relationship between Dr. Jekyll and Mr. Hyde, and he wants to find out. Also, by omitting the scenes of Mr. Hyde’s supposedly crazy debauchery, Stevenson allows our imaginations to run to wild and eerie places.

Violence

Strange Case of Dr. Jekyll and Mr. Hyde details two crimes of Violence against innocent and helpless citizens: first, a little girl, and second, an elderly man. The violence in the novel centers on Mr. Hyde, and raises the question of whether or not violence is an inherent part of man’s nature.

Religion

God and Satan figure prominently in Strange Case of Dr. Jekyll and Mr. Hyde, as well as many general references to religion and works of charity. As part of their intellectual lives, the men in the novel discuss various religious works. One sign of Mr. Hyde’s wickedness, for example, is his defacing Dr. Jekyll’s favorite religious work.

Women & Femininity

Most female characters in Strange Case of Dr. Jekyll and Mr. Hyde are passive and weak. The first female we see is a young girl mowed over by Mr. Hyde. Although she is "not much the worse, more frightened," she still kicks up an incredible fuss and a large group of people come to her aid.  The next woman we see is the maid who witnessed the Carew murder. After watching Mr. Hyde beat the man to death, she faints, waking up long after the murderer is gone. She is a passive spectator.
