The ending (Scene 3) is a tragic one, where all of the main characters relevant to the plot (besides Edgar, Albany, and Kent(who later plans to kill himself)) are killed off. Edmund is killed by Edgar, Gloucester dies of a heart attack, Cornwall is killed by his servant, Regan is poisoned by Goneril (who kills herself), Cordelia is hanged, Lear dies of sadness, and even his fool is hanged.
