One of the facets of the brilliance of Shakespeare is that there are no simple solutions. His plays, like life, are complicated and the results, more often than not, are less than ideal. What joy one should take in the happy resolutions of his comedies, and what warning should one should take in the dark explorations of the tragedies. King Lear, if not his masterpiece, is one of his best. The exposition of Lear's temperament (in our day, we might call it his descent into senility, the loss of his rational mind) is moving -- having glimpses of understanding what he's done to his best and youngest, it breaks his heart. As others have noted, the ending of the play is not without redemption, as at least one of the good guys, Edgar, survives. But not all the guilty are punished, and not all the innocent are free. That's the hard nature of tragedy.
