Each of us has heaven and hell in him, Basil.
Dorian names the split inside him at a breaking point. The heaven/hell pairing sharpens the inner conflict that the portrait literalizes. It’s the most honest thing he says—confession and warning in one breath. The line also hints that influence isn’t the whole story; something in Dorian answers Henry’s ideas. By putting both realms inside one person, Wilde removes the safety of “good people” and “bad people.” The moment is raw, and the room feels smaller for it. Readers feel the tragedy of clarity arriving too late.
