Strange case Of Dr. Jekyll and Mr. Hyde

Stevenson writes about the duality of human nature – the idea that every single human being has good and evil within them. Stevenson describes how there is a good and an evil side to everyone's personality, but what is important is how you behave and the decisions you make. The choices people make determine whether a person is good or not. In Dr Jekyll and Mr Hyde, Dr Jekyll is a well-respected, intelligent scientist who secretly has a dark, immoral side to his personality. This side of his personality is not active, however, he decides to activate it through his experiments. This side becomes active through the persona of Mr Hyde - a criminal man who commits cruel acts of violence against others. Through this change in Jekyll's character, Stevenson shows the duality in human nature - the idea that everyone is capable of good and evil deeds.
