It is obvious that Mr Hyde is an evil man from the first incident. It was "about three o'clock of a black winter morning" when Mr Enfield saw "a little man stumping along" and "trampled calmly" over a young girl and "left her screaming". It is clear that he seems unstopable like a "damned Juggernaut.
In the search for hyde, Utterson goes to confront Hyde when Hyde, "shrank back with a hissing intake of breath." Very much like a snake which is believed to be the image of the devil. When Utterson mentions Jekyll, Hyde firstly loses his temper. He then answers with, "Jekyll wouldn't have told you!" This means that there is something going on between Jekyll and Hyde, and it is probably more than simple blackmail which creates tension.
Hyde then quickly finishes the conversation and then runs inside his house. Utterson's thoughts on the way back to his house describe Hyde as, "hardly human", and that he regards him with, "unknown disgust, loathing and fear.
Another example of Hyde's evil is in the killing of Sir Danvers Carew. Sir Danvers appears to have been killed for no apparent reason. The murder of Sir Danvers was seen by a maid who was working nearby. The book states that there was a "beautiful gentleman with white hair" and meeting him was "a very small gentleman", it is clear to the reader that this individual is Edward Hyde, this creates tension. After the two exchanged words, the maid "recognises in him a certain Mr Hyde", this adds to the tension and gives suspense. But suddenly he bursts out and threatened him with the cane, "broke out of all bounds" and battered him to the ground. Hyde is considered to be "like a madman" and have an "ape-like fury", this gives the reader fear, disgust and loathing.This tells us the reader that Mr. Hyde has grown in fury. From trampling over a child in the first scene, he now commits murder for no reason.
In Doctor Lanyon's Narrative, the messanger for Jekyll "was dressed in a fashion that would have made an ordinary person laughable", this description gives us a clue that this person is Mr Hyde and creates tension. Mr Hyde puts a glass to his lipsand appears as Henry Jekyll, this creates tension and suspense as we wonder what happens to Dr Lanyon.
