You, who call Frankenstein your friend, seem to have a knowledge of my crimes and his misfortunes. But in the detail which he gave you of them he could not sum up the hours and months of misery which I endured wasting in impotent passions. For while I destroyed his hopes, I did not satisfy my own desires. They were forever ardent and craving; still I desired love and fellowship, and I was still spurned. Was there no injustice in this? Am I to be thought the only criminal, when all humankind sinned against me?
