Prospero is wise and extremely resourceful because he has magical powers. His wisdom makes him tolerant and charitable at the end of the play. However, he never reconciled completely with his brother. He treats him with studied contempt and neglect. He only gave him a brief verbal pardon and otherwise hardly addresses a word to him. In reality, there is anger against his enemies beneath the grant of pardon.
He becomes a terrible old man. But he is also a noble, kind and generous person. He forgives all his enemies. Moreover, his forgiveness is not only solemn and judicial but also abstract and impersonal. He does not act against his own noble deeds.
