Answer
Prospero is discussing with Ariel about the possibility of him becoming tender towards the people he has wronged. Ariel believes that Prospero would become tender if he were to see their afflictions. Prospero agrees and states that he, being one of their kind, would be moved even more than Ariel. Despite being struck to the quick by their high wrongs, Prospero chooses to take the nobler action of virtue over vengeance. He instructs Ariel to release them and restore their senses.
