Macbeth

Arguably the darkest of all Shakespeare's plays, Macbeth is also one of the most challenging. Is it a work of nihilistic despair, "a tale told by an idiot, full of sound and fury, signifying nothing," or is it a cautionary tale warning of the dangers of Machiavellianism and relativism? Does it lead to hell and hopelessness, or does it point to a light beyond the darkness?
