You can't say that there's no poetic justice at all in Shakespeare's
King Lear. True, he wasn't a firm believer in happy endings, yet it wasn't like Martin Scorsese's film
The Departed where literally everyone dies at the end. However, Shakespeare did deal out some poetic justice. Goneril and Regan, for example, who manipulated their father and his disintegrating state of mind and body for their own gain, both died in the end. Isn't that poetic justice? They got what they deserved, didn't they?
And then there's Lear himself. He chose Goneril and Regan, who lied and showered him with false flattery, over Cordelia, who was honest and true. Then, ironically, the two daughters betrayed their father and banished him from his own kingdom. (Well, Lear, that's what you get.) But this betrayal by two of his daughters led to the reconciliation with his other daughter. For a while, we all thought there might be a happy ending -- but that, of course wasn't the case. And thats what KD meant about no poetic justice.
And then there's Edmund. He set out to be evil because he believed it was his destiny, and he did his best to fulfill his destiny. He pitted his father against his own brother, Goneril against her own sister Regan, and was the reason Cordelia and Lear didn't have their happy ending. But in true poetic justic fashion, in the end, Edmund dies too.
Shakespeare wasn't a fairy tale writer -- at least not in
King Lear. There's no happily ever after, but there is poetic justice. It might not be as relevant as all the unfairness and cruelty that goes on, but it is still there.
