What contrasts are implied between Macbeth and Edward the Confessor in act 4 scene 3?

I think the largest contrast lies in the fact that the English Monarchy had to be portrayed as the antithesis of the villain in the story. Shakespeare well knew Elizabeth the 1, who liked theatre, was judging his plays. Shakespeare’s tragedies take place away from England. The further away from England, the more chaotic things get. King Edward represents Godly judgment. Edward’s wisdom and charity must represent the opposite of the tyrant Macbeth’s rash and evil behavior.
