These aspects about evil have been already seen on the previous pages, but the main idea is that on the surface we can think that Hyde is evil but in the inside we can see that the evil is Jekyll, who is Hyde.

Henry Jekyll has two faces: the good and respectable Henry Jekyll, with a strong morality and ethical principles, and the "bad and ugly" Edward Hyde, amoral and violent (who is, in fact Henry Jekyll, too).

Jekyll is the good and the bad character of the story, he feels remorse for what Hyde does but as if another being did it (in fact he does it himself).

Stevenson structures the novel following what we have said related to the Victorian Home: the back door, the one used by Hyde to enter the house, represents the entrance of evil. Crime, vice... evilness in general is committed in the poor areas, that are those in which Mr.Hyde acts (he trampled a girl there and he killed a man in those districts).

In Victorian novels, crime and vice are related to poor areas, in which life is harder, while virtues and social conventions are placed in residential areas.

What Stevenson depicts is that evil enters (through the back door) also to the residential areas, and have a strong influence in Lanyon and Jekyll, who become "enemies" because Lanyon is not brave enough to make the same experiments Jekyll had made, for his moral principles and because he is afraid of the consequences.

To sum up, Stevenson shows the effects of evilness in mankind, apart from economical considerations
