Dr Jekyll - The Respectable Gentleman

Jekyll starts as everything Victorian society admired: intelligent, handsome, wealthy, and well-mannered. He's got a solid reputation and seems like the perfect gentleman on the surface.

But here's where it gets interesting - Jekyll believes that "man is not truly one, but truly two". This idea drives him to create a dangerous potion that separates his good and evil sides. At first, he actually enjoys transforming into Hyde because it lets him act without consequences.

However, things spiral out of control quickly. Jekyll becomes erratic and dependent on his transformations, eventually admitting that "if I am the chief of sinners, I am the chief of sufferers also". The man who once controlled the experiment becomes controlled by it.

Remember: Jekyll represents how even the most respectable people can harbour dark desires beneath the surface.

Mr Hyde - Pure Evil Unleashed

Hyde is absolutely terrifying - not just because he's violent, but because he makes people feel physically sick just by looking at him. Witnesses describe him as having "ape-like fury" and giving off "unknown disgust, loathing and fear".

The bloke doesn't just break social rules; he tramples over them literally and figuratively. He tramples a young girl without a care, then later murders the respected MP Carew in a fit of rage. These aren't crimes of passion - they're acts of pure, calculated cruelty.

What makes Hyde even more disturbing is how he gradually takes control of Jekyll's mind. The relationship shifts from Jekyll controlling Hyde to Hyde dominating Jekyll, showing how evil can consume someone completely.

Key insight: Hyde represents the consequences of trying to separate morality from human nature.

Utterson - The Loyal Friend

Meet Utterson, the loyal lawyer who becomes our window into this bizarre story. He's described as "somehow loveable" despite being quite serious - a man who "never lighted by a smile" but genuinely cares about his friends.

When Utterson declares "if he shall be Mr Hyde, I shall be Mr Seek", he shows his determination to protect Jekyll. His curiosity and concern drive the investigation, even when Jekyll warns him "You must suffer me to go my own dark way".

Utterson represents Victorian respectability, but unlike Jekyll, he doesn't try to split himself in two. Instead, he channels his curiosity constructively by investigating the mystery. He reads Jekyll's will, questions witnesses, and eventually uncovers the terrible truth.

Think about it: Utterson shows that being genuinely good means facing uncomfortable truths, not hiding from them.

Evil - The Monster Within

Evil in this story isn't some external force - it's internal and personal. Hyde doesn't just hurt people; he "trampled calmly over the child's body", showing complete lack of empathy or remorse.

Stevenson uses powerful imagery to show evil's presence. Jekyll's lab "showed no window", symbolising the secrecy and hidden corruption within. Even Hyde's landlady has "an evil face, smoothed by hypocrisy" - evil hides behind respectable facades.

The most chilling aspect is how evil corrupts everything it touches. Hyde beats Carew to death partly because evil naturally hates good. The story suggests that trying to separate our dark impulses doesn't eliminate them - it makes them stronger and more dangerous.

Critical point: The novel argues that evil becomes more powerful when we try to deny or separate it from ourselves.

Repression - The Dangerous Game

Repression - hiding or suppressing natural impulses - is what drives the entire tragedy. Jekyll doesn't want to deal with his darker thoughts, so he tries to literally separate them through science.

The consequences are explosive. As Jekyll explains, "My devil had been long caged, he came out roaring". When we bottle up parts of ourselves, they don't disappear - they build pressure until they burst out more violently than before.

Even supposedly moral characters like Utterson repress things. He admits "I am ashamed of my long tongue" about his curiosity, showing how Victorian society made people feel guilty about natural human traits.

The physical transformation of Jekyll - his "large handsome face" developing "blackness about his eyes" - shows how repression literally corrupts us from within.

Essential understanding: The novel warns that healthy self-acceptance is better than trying to deny parts of our personality.
