Frankenstein - Mary Shelley

The monster saw my determination in my face and gnashed his teeth in the impotence of anger. "Shall each man," cried he, "find a wife for his bosom, and each beast have his mate, and I be alone? I had feelings of affection, and they were requited by detestation and scorn. Man! You may hate, but beware! Your hours will pass in dread and misery, and soon the bolt will fall which must ravish from you your happiness forever. Are you to be happy while I grovel in the intensity of my wretchedness? You can blast my other passions, but revenge remains−revenge, henceforth dearer than light or food! I may die, but first you, my tyrant and tormentor, shall curse the sun that gazes on your misery. Beware, for I am fearless and therefore powerful. I will watch with the wiliness of a snake, that I may sting with its venom. Man, you shall repent of the injuries you inflict."
