There's a hell and a heaven inside all of us

Everybody has a good and a dark side, it’s in our nature and it’s impossible to change it. These sides are very different from each other.

The evil side is a moment or a little period of time that you’re full of rage and you don’t think about the consequences of your actions, and it depends on the people. Oscar Wilde compared these two sides of the people with the heaven and the hell. In this story, this evil side appears when Dorian killed Basil.

The good side is shown in your routine and it’s what we want to show to the people to cause a good impression. This side appears in the story when Dorian is with Mr. Henry.

The duration of these sides depends on the person, specially on his temperament and his environment.
