Jekyll is a kind and respected English doctor who has repressed evil urges inside of him. In an attempt to hide this, he develops a type of serum that he believes will effectively mask his dark side. Instead, Jekyll transforms into Edward Hyde, the physical and mental manifestation of his evil personality.

Was Hyde or Jekyll evil?

Jekyll's transformed body, Hyde, was evil, self-indulgent, and uncaring to anyone but himself. Initially, Jekyll controlled the transformations with the serum, but one night in August, he became Hyde involuntarily in his sleep. Jekyll resolved to cease becoming Hyde.

How is Jekyll presented as evil?

Jekyll says Hyde is 'alone in the ranks of mankind, pure evil' (p. 61). His evil lies in being entirely selfish: he will do whatever he wants to satisfy his own appetites without any regard for other people.
