The mission of Malvolio is to bring to the play an element of drama and realism. He is gloomy, practical and serious. He does not allow himself to have fun because for him it is just an idle use of time. He appreciates the respect for decency, good tone, and decency. But Malvolio is not devoid of human feelings, experiencing tenderness and affection for Olivia. Not knowing how to show his favor, he often puts himself in an awkward position. The other heroes despise him for fanatical puritanism, although Olivia highly appreciates his qualities. Malvolio becomes a victim of jokers. But he does not cause sympathy, because it is not so much driven by pure love, like vanity and the opportunity to advance in the service.
