Who is the more forceful character Macbeth or lady Macbeth?

The more dynamic person is Macbeth because in the beginning he is unsure whether or not kill the King or to remain loyal to him. However, he is persuaded by his wife Lady Macbeth, - who by the way is a static character - to kill the King. After he kills the king, Macbeth's ambition does not only drive him to do great things, it spins him out of control and begins to take over him.
