Great God! If for one instant I had thought what might be the hellish intention of my fiendish adversary, I would rather have banished myself forever from my native country and wandered a friendless outcast over the earth than have consented to this miserable marriage. But, as if possessed of magic powers, the monster had blinded me to his real intentions; and when I thought that I had prepared only my own death, I hastened that of a far dearer victim.

– Mary Shelley

Frankenstein, Chapter 22. Despite the creature warning that he will be with him on his wedding night, Victor goes ahead and marries Elizabeth. Appearing to believe the monster was just targeting him and not Elizabeth, he lives to regret this.
