Answer: Macbeth could have stayed King, but he would have been doomed eventually. Macbeth made a series of bad decisions that were driven by his ambition, which ultimately led to his downfall. He killed King Duncan, which led to an uprising, and he also killed Banquo, which led to more unrest. He also had a tendency to listen to the prophecies of the witches, which likely led to more chaos and confusion. Ultimately, Macbeth's ambition was his downfall, and it is likely that he would have eventually been toppled from power.
