Macbeth is. Nor is it the only one of Shakespeare's plays where the main character is the villain. Richard III (a very similar play) is another example. Marlowe did it too e.g. The Jew of Malta.
whatever it wants to be
Macbeth
The main character in the play "Macbeth" is of course Macbeth
Macbeth and Lady Macbeth.
The main villain in Final Fantasy VII is Sephiroth
Macbeth's supernatural encounter propels his actions. Yes, Lady M. encourages him: "Thou shalt be what thou art promised". She is decisive, unwavering. Ultimately, however, Macbeth takes matters into his own hands with additional unplanned murders. They both have free will. It is too simplistic to label her her as the "villain" or "evil". The complexities of the marriage, power, ambition, and fate are much more interesting!!
Mrs. Danvers, the housekeeper, is the main villain in Rebecca.
A pantomine villain is someone who hates the main character... :)
