Jekyll's Secret Life and Scientific Obsession
Jekyll wasn't always the respectable gentleman everyone thought he was. From early on, he lived a double life - outwardly focused on scientific work whilst secretly indulging in "disgraceful pleasures" that would've destroyed his reputation if discovered.
The pressure of maintaining his family's good name whilst hiding his true desires created an "almost morbid sense of shame." This constant internal battle led Jekyll to a radical conclusion: "Man is not truly one but two." He believed everyone has both good and evil sides fighting within them - a pretty controversial idea in religious Victorian society.
Jekyll's scientific interests turned towards the "mystic and transcendental" - basically, he became obsessed with occult experiments that his colleague Lanyon found disgusting. His goal was ambitious yet dangerous: to separate the good and evil elements of human nature into two distinct beings.
Key Point: Jekyll thought he could create pure good and pure evil versions of himself, freeing his respectable side from dark urges whilst letting his wicked side act without conscience.
The Transformation and Hyde's True Nature
The actual transformation scene is pure gothic horror. Jekyll describes "racking pangs" and violent physical changes as his body shrinks and contorts into Hyde's form. But here's the twist - Hyde starts off weak and small because Jekyll's evil side hasn't been "exercised" much yet.
Hyde grows stronger with each evil act committed, just like Dorian Gray's portrait becoming more corrupted. Everyone instinctively fears Hyde not because of physical deformities, but because their souls recognise his "pure evil" nature - he's essentially described as Satan himself.
Jekyll's plan backfired spectacularly. He only succeeded in separating out his evil half, whilst he remained a mixture of good and evil. This suggests Jekyll massively underestimated how much darkness was within him - the evil side was always stronger than he realised.
The transformation initially felt liberating - like a "schoolboy" stripping off restrictions to "spring headlong into the sea of liberty." Jekyll could now indulge in sinful pleasures without consequences to his reputation.
Remember: Hyde isn't a separate person - he's Jekyll's repressed desires finally set free, which explains why he becomes increasingly difficult to control.
Loss of Control and Growing Evil
Things quickly spiralled out of Jekyll's control. The biblical reference to "the Babylonian finger on the wall" warns that Jekyll has been "judged and found wanting" - essentially, he's doomed. Hyde's body grows larger and stronger whilst Jekyll weakens, showing that evil is winning the internal battle.
Jekyll's hypocrisy becomes clear here. He creates Hyde to live out sinful desires without consequences, but then suppresses him when convenient. He only cares about his reputation, not the harm Hyde causes - making Jekyll arguably more monstrous than Hyde himself.
The relationship between them shifts from creator-creation to something like father-son, with "Jekyll having more than a father's interest; Hyde more than a son's indifference." Jekyll even leaves the transformation drug ready in his cabinet, showing he never truly intended to give up his evil alter ego.
When Jekyll's "devil had been long caged, he came out roaring" after the Carew murder. This represents Jekyll's complete loss of moral control - he's stripped himself of all "balancing instincts" that keep humans civilised.
Critical Insight: Jekyll claims moral superiority over Hyde, but he's the one who created this monster and continues enabling him for selfish reasons.
The Final Transformation and Jekyll's Doom
The story reaches its climax when Jekyll loses permanent control. He goes to bed as Jekyll and wakes up as Hyde, showing that his evil side now dominates completely. The transformation happens involuntarily, and Hyde grows stronger whilst Jekyll becomes "shaken, weakened."
Jekyll's realisation is terrifying: "powers of Hyde seemed to grow with the sickliness of Jekyll." The evil wins because Jekyll's secret desires were always stronger than his public respectability. He starts referring to himself in third person, showing he's losing his very identity.
Hyde develops his own agenda, resenting being suppressed and hating Jekyll just as Jekyll rebelled against society's restrictions. It's perfectly ironic - Jekyll created Hyde to escape control, but now Hyde rebels against Jekyll's control.
The practical problem that finally dooms Jekyll is almost anticlimactic - his original drug supply was impure, and he can't recreate the formula. Without it, he can't transform back from Hyde.
Tragic End: Jekyll accepts his fate, knowing that when the drug runs out, only Hyde will remain - essentially meaning Jekyll's death and Hyde's victory.
