Hell is empty,
And all the devils are here.
– William Shakespeare
The Tempest, Act 1, Scene 2. Ariel to Prospero, relating what Ferdinand cried out as he plunged into the water from the shipwreck. Ferdinand recognizes the true and evil nature of his father King Alonso and the royal party with whom he traveled. In the full quote, Ariel uses a simile to compare Ferdinand’s hair to reeds: "Then all afire with me: the king’s son, Ferdinand, With hair up-staring, – then like reeds, not hair, – Was the first man that leaped; cried, ‘Hell is empty And all the devils are here.’"
