In "Frankenstein", how does the creature convince Victor to make him a mate?
The creature tries to appeal to Victor's emotions as well as his sense of responsibility as a creator. The creature says,
I am thy creature, and I will be even mild and docile to my natural lord and king if thou wilt also perform thy part, the which thou owest me. Oh, Frankenstein, be not equitable to every other and trample upon me alone, to whom thy justice, and even thy clemency and affection, is most due. Remember that I am thy creature; I ought to be thy Adam, but I am rather the fallen angel, whom thou drivest from joy for no misdeed. Everywhere I see bliss, from which I alone am irrevocably excluded.
In other words, the creature describes himself as a victim. He implies that Victor, his creator, has dealt fairly with everyone else in his life except the creature. The creature claims that Victor owes him the chance to be happy. In fact, he claims that Victor owes him mercy and affection because he is his maker. He appeals to Victor as to a god, perhaps stroking his ego a bit, saying that he should be Victor's prized and loved creation, but he is, instead, punished and ostracized for no fault of his own. He appeals to Victor's sense of justice, describing the happiness everyone around him can share but of which he, alone, can never partake. He desires a companion to alleviate the pain of solitude.
Further, the creature describes the horrible treatment he's received from all of humanity. He says, "These bleak skies I hail, for they are kinder to me than your fellow beings." He knows that he will never be accepted by humanity, due to his horrible appearance; therefore, he must have a mate as physically ugly as he. He says, "I am alone and miserable; man will not associate with me; but one as deformed and horrible as myself would not deny herself to me. My companion must be of the same species and have the same defects." A mate will cure his loneliness, and he believes that Victor owes him at least a chance to be happy.
The creature appealed to Victor's guilt and fear. He tells Victor that because of the way he was created, he is the one creature in the world that is totally alone. All other creatures can have a mate to share their life with; he has no one. That appeals to Victor's guilt. The appeal to fear is more direct. The creature tells Victor that the only way to stop his killing spree, the only way to guarantee that Victor will no longer be a murderer.by.association, will be to create him a mate. He promises that he will go off with her, never to be seen again, never to kill again.
Victor is consumed by fear and guilt, and he is willing to do anything to "atone" for his son's/creature's action is at first willing to go along with this. In the process, however, he changes his mind and destroys the "mate." It's interesting to discuss why he did this. He says that he didn't want to create a race of "creatures," but how difficult would it have been to create a sterile mate? Probably no more difficult than making a functioning creature ... but, then, it would be a totally different story.
The creature uses two techniques: fear and guilt.
Victor already realizes that the creature that he has created is responsible for the murder of his younger brother and, in turn, the execution of one of his closest friends. The creature guarantees Victor that he will allow no happiness and much more death and destruction if Victor does not create a mate.
Also, the monster appeals to Victor's sense of guilt. He tells Victor about how horrendous his 'life' has been as he has wandered from place to place in search of love only to be rejected at every turn.
