Respuesta :
In the novel's final chapter, Jekyll's letter emphasises one of the novel's central themes: man's dual nature.
Dr. Jekyll and Mr. Hyde:
This was his motivation for carrying out his dangerous experiments, which ultimately led to his demise.
Hyde, the expression of Jekyll's totally malevolent tendencies, enjoys his anonymity. Despite his expertise in extracting his dark side, Jekyll is still a blend of good and evil. As a result of years of repression, his evil side grows stronger and more powerful, and he can completely control himself as he transforms back and forth.
In this way, Jekyll's experiments are the polar opposite of what he anticipated. As mentioned multiple times throughout the novel, Hyde is a small man, frequently referred to as dwarfish, whereas Jekyll is a large man. As a result, the reader gets the feeling that Jekyll's evil side is much weaker and less developed than his good side. However, appearances can be deceiving. In fact, Hyde's strength far eclipses Jekyll's.
"Henry Jekyll stood at times aghast before Edward Hyde's actions," Jekyll writes in his letter, "but the circumstance was distant from customary laws, and insidiously loosened the clutch of conscience." After all, it was Hyde, and only Hyde, who was at fault.
