Mr Hyde is described as devilish, evil, and a criminal mastermind. His first appearance in the novel shows him violently trampling a young girl. His violence continues, and he eventually murders Sir Danvers Carew.

Hyde is Jekyll's evil side made flesh. He is smaller and younger than Jekyll suggesting that Dr Jekyll's good side is larger than his bad and that his evil side develops later in life than the good.

Stevenson makes Hyde more mysterious by only hinting at his physical appearance. We know that people are deeply affected by his appearance though.

quote
There is something wrong with his appearance; something displeasing, something downright detestable. I never saw a man so disliked.Dr. Jekyll and Mr. Hyde, Robert Louis Stevenson

Hyde is unforgiving and doesn’t repent for his crimes or sins. He is selfish and wishes for complete dominance over Jekyll

EvidenceAnalysis
"he broke out in great flame of anger... carrying on like a mad man"Description of Hyde murdering Sir Danvers Carew. Shows Hyde's lack of self-control.
"with ape-like fury, he was trampling his victim under foot and hailing down a storm of blows"Shows the brutality of Hyde's attack.
"I never saw a man I so disliked and yet I scarce know why."Enfield's description of Hyde's physical appearance.
"He must be deformed, he gives a strong feeling of deformity, although I couldn't specify the point..."Enfield cannot put his finger on what it is about Hyde that is “deformed”.
"Mr Hyde shrank back with a hissing intake of the breath..."The word "hissing" again shows Hyde's animalistic qualities.
"Mr Hyde was pale and dwarfish, he gave an impression of deformity without any nameable malformation, he had a displeasing smile..."Utterson's description of Hyde echoes Enfield's description. The characters that meet Hyde are all convinced that something is "wrong" with him but cannot pinpoint what it is.
"unknown disgust, loathing and fear"Again, Utterson reacts to Hyde in a similar way to Enfield. The reaction of disgust is common to all who meet Hyde.
