Macbeth

Is Macbeth really the wimp in the story? He after all is the one that provides Lady Macbeth with doubt..... Which leads to the question of whether Lady Macbeth is the true villian in the story? (If she is a villian or just an ambitious woman)

another question

Could it be that the story of Macbeth is not about ambition but about fear? Macbeth's actions after his first murder are after all driven by fear of someone finding out...
