Response to Morgan

Morgan, I agree that enough will never be enough for MacBeth.  He has dug himself such a deep hole that it is impossible to repent for his sins.  You said he had the choice to run away, continue to kill or kill himself.  Here is where I think you are wrong.  None of these options sound like the character of MacBeth, besides, perhaps, continuing to kill.  Instead I believe that MacBeth chooses to show the power he holds to intimidate anyone apposing his throne.  At this point, many people suspect MacBeth as a psychopathic murderer.  Instead of killing anyone he suspects, I believe the next step for MacBeth is to blot out any uprising by becoming the ultimate tyrant that no one dares to cross.  Either way, the downfall of MacBeth is unavoidable as Shakespeare writes to prove a point about the destructive capabilities that unbridled ambition and lust for power can have on a human being.
