GLOUCESTER: Alack, alack, Edmund, I like not this unnatural dealing. When I desired their leave that I might pity him, they took from me the use of mine own house, charged me on pain of perpetual displeasure neither to speak of him, entreat for him, or any way sustain him.
EDMUND: Most savage and unnatural.
– William Shakespeare
King Lear, Act 3, Scene 3. Goneril and Regan have taken charge of Gloucester’s castle and ordered him not to speak to Lear, appeal on his behalf, or care for him in any way. In this passage he complaints bitterly about the "unnatural" behavior of Lear’s daughters and Edmund quickly agrees. There is dramatic irony here, as the audience knows that Edmund cannot be trusted and is deceiving his father. Edmund is putting on a pretence of being outraged, while Gloucester is blind to his duplicity.
