Lear and the Plan of Salvation

When we were discussing comedy, one point Professor Burton made was that a hallmark of comedy is the eventual return to order after the limits have been tried. What impressed me about the end of King Lear, was how this same principal works within the tragedy. At the end Cordelia, Gloucester, and King Lear die from punishments beyond their crimes, but Edgar and Albany are left. Both have gained from their experience and both are qualified to lead the nation out of the darkness that the tragic experiences produced. Order was questioned, but the bastard was killed, Lear vindicated, Cordelia exalted to a saint, and the kingdom was restored again to order.
I think that this has to do with the redemptive power found in tragedy. Although punishment and suffering normally exceed what characters deserve in tragedy, by the end, the world moves on from it, being slightly bettered for having learned something from the experience. An article by Duncan S. Harris, found at this link, goes further in explaining how ultimate balance is restored. He linked Shakespeare's plays with Christianity and said that the clarity that we receive at the end, from having the tale wrap up and the morals revealed, allows us to, in LDS terms, look towards the promised last judgement, when all that is dark will be revealed and the world will have clarity. At the end of a tragedy there is no guarantee that another tragedy will not occur, but it does act as a metaphor, giving hope for when all will be revealed at the last day. The suffering will end in the ultimate end.
