Hyde also creates terror; the servants are extremely frightened of him. When they think he is around the house, the servants cringe in horror, and some go into hysterics.
As the novel progresses, Hyde's evil becomes more and more pronounced. He bludgeons Sir Danvers Carew to death for absolutely no reason other than the fact that Sir Danvers appeared to be a good and kindly man — and pure evil detests pure goodness.
Since Hyde represents the evil or perverse side of Jekyll, and since Jekyll does, vicariously, enjoy the degradations which Hyde commits, Hyde gradually begins to take the ascendancy over the good Dr. Jekyll.
A conflict between them erupts, as though the older Dr. Jekyll is a father to the errant and prodigal son. He wants to punish this son, but at the same time, he recognizes that Hyde is an intimate part of himself. Ultimately, when Jekyll commits suicide in order to get rid of Hyde (suicide is an evil act in the eyes of the church), this allows Hyde to become the dominant evil figure, and the dying Jekyll becomes Hyde in the final death throes.
