In Macbeth, how is the natural and moral order restored, and how is it shown in the play?How is the chain of being and social hierachy restored?

From the time Macbeth kills the rightful king and usurps
the throne, nature is thrown out of order.  There are numerous reports of unnatural
actions in nature itself after the murder.  Since Duncan was the "Lord's annointed" and
Duncan has been murdered things will not be normal until the murderer is brought to
justice. 

Since Duncan had named his successor before he
was murdered, order will be restored when Malcolm is crowned
king. 

Curiously, the supernatural plays a great role in
all this.  First the weird sisters declare Macbeth will be king.  Lady Macbeth calls up
the dark powers to unsex her and fill her with evil.  Both of the Macbeths go to the
dark side.

Since Macbeth tries to interfer with the
predictions by killing Banqueo, Hacate herself gets involved.  The predictions that he
believes keep him safe are a double edged sword.  The forest does indeed move and
MacDuff was not "born" of woman but was from his mother's womb untimely
ripped.

It is only fitting that it is MacDuff rather than
Malcolm who kills Macbeth since Macbeth killed his entire family.  Order is restored and
nature has been balanced.

An orderly succession and order
were extremely important to the Elizabethean world.  The War of the Roses was a recent
memory and the entire country had been ripped apart on the question of
succession.
