"The Tempest" is considered a revenge tragedy. The usurpation of Prospero's dukedom from Antonio, his own beloved brother, is an indication of his distemper. Words that can create a tone of reproach and melancholy for the past are: "evil nature", falsehood", "perfidious" which are attributed to the dishonest brother. Miranda appears to live in a dream place where corruption and malevolence do not exist. However, Prospero's negative attitue towards Antonio expresses that there is evil in human nature and it can even come from close acquaintances and family.
The theme is to not underestimate the abilities of something or someone based on its size. This is because the lion thought he was superior to the mouse, until one day the mouse was able to rescue him.
