what is a good thesis statement for a research paper over macbeth and how superstitions played a role in macbeth

You need three firm concepts for your thesis. If you're looking at superstitions, you can begin with Macbeth & Lady Macbeth's disbelief of the witches' predictions. Second, you have the fact that they believe themselves to be the fulfillment of the prophecy, that Macbeth is destined to be King. Lastly, you might consider addressing Macbeth's belief that since he's already committed murder, further action (killing and violence) are acceptable because he's already doomed. Or you might want to insert personal experience and cite the effects of superstition in today's modern world with the world of Shakespeare.
