Answer:
It shows how, while rightful kings bring order to their nation, tyrants bring disorder.
Step-by-step explanation:
In Macbeth you can read:
"Each new morn,
New widows howl, new orphans cry; new sorrows
Strike heaven on the face, that it resounds
As if it felt with Scotland, and yell'd out
Like a syllable of dolour."
This is a reference on how the rightfull heir to the throne and the right king will bring peace and order to his nation, while tyrans only want what´s best for them and the people will end up suffering from having them in power.
