The play’s denouement involves the deaths of many of the characters, most of them violent. Edgar kills his brother Edmund. Edgar also unintentionally kills his father, who is overcome by the discovery that his son has survived and forgives him. Edgar is restored to power, as the new Duke of Gloucester, but like Edmund he has had to destroy his family to do it. Lear’s family is also destroyed. Regan, Goneril, Cordelia and finally Lear himself all die. The center of the denouement is Cordelia’s death. Even though Edmund reverses his orders to have Cordelia and Lear killed, his decision comes too late. This truth echoes the fatalism of the entire play – a mistake, once made, can’t be undone, just as Lear can’t undo his fatal mistake of giving the wrong daughters his kingdom. In the play’s final scene Lear carries Cordelia’s body onstage, howling with grief. Lear has finally learned to love his daughter without asking for anything in return, only to have her taken from him. All Lear’s suffering has been for nothing.
The climax of the play comes when Edgar kills Edmund and unintentionally kills his father, who is overcome with grief about his son's survival. This parallels Lear's family misfortunes as Regan, Gonerial, Cordelia, and King Lear all die. As Lear can't undo his fatal mistake of giving the wrong daughters his kingdom, so can this truth echo the fatalism of the entire play.
