What are some themes found in the play Macbeth?

Answer 1

1) Ends don't justify means, because what is ill-gotten is corrupt and will colapse or fail because of the way it was acquired. Thus MacBeth's government must fail.

2) Destiny will be fullfilled. The plot has unexpected twists to make the three witches' prophesies come to pass. But they do ... in spite of MacBeth's efforts to hold power.

Answer 2

good versus evil (witches turn good into evil)
