how does the monster reason with Victor?

The creature wants Victor to make a mate for him. Victor argues that their "joint wickedness" would be enough to destroy the world. The creature replies by saying that he is only malicious as a result of his misery: why should he meet man's contempt with submission? If he is met with hatred, he can only respond in kind. He appeals to Victor for sympathy, and asks Frankenstein to provide him with a lover to share in his suffering. If he complies, the creature promises to quit the company of mankind forever.
