By creating Hyde, Jekyll breaks the balance between good and evil within himself. Without this balance, Jekyll cannot survive. Each time Hyde becomes active, he gains more power over Jekyll and ultimately leads to his downfall. Hyde started out as small things that Jekyll refrained from doing or even thinking because he knew he would not be accepted by society if he indulged in them, but as he became more powerful , small “undignified” pleasures turned into murder, and other horrible and heinous crimes. The evil that Hyde possessed transformed into something uncontrollable, while Jekyll remained Jekyll, neither purely good nor purely evil. Ultimately, Hyde's evil overwhelmed Jekyll's normalcy. Perhaps there was a reason why society initially prompted Jekyll to suppress Hyde within it.
