As far as my observation goes, there are
two change of roles that occurred within the play; the one with Kent and Edgar.
Kent, the former earl, ends up
disguising himself as a low life servant for his former adversary, King Lear. After
being banished by Lear as a result from Lear’s own arrogance in not accepting
or even hearing Kent’s advice relating to his way of ruling the land. Despite
the fact of his banishment from the kingdom, Kent’s love and compassion for the
king and the kingdom is far too great to make him surrender. Thus, he decided
to try different approach in giving Lear guidance, by becoming one of his trusty
servants.
