In Chapter 10 of Frankenstein, why does the creature say he feels as he does about mankind?
In torment as he realizes that he, in effect, has been the true murderer of his brother William, Victor resolves to locate the monster that he has made and destroy it. And, when he sees him approaching, Victor is filled with "furious detestation and contempt." However, the creature stays Victor, telling him of his only physical prowess. He also demands that Victor listen to him before venting his hatred upon his "devoted head":
I am thy creature and I will be even mild and docile to my natural lord and king, if thou wilt also perform they part, the which thou owest me.
The creature claims the right to speak; if, after he finishes, Victor wishes to destroy him, he will allow Victor to try. Then, likening himself to the "fallen angel," when he should be Victor's Adam, the creature says that he was driven away from joy for "no misdeed" as Victor's fellow-creatures spurn and hate him for no reason:
Everywher I see bliss, from which I alone am irrevocably excluded. I was benevolent and good; misery made me a fiend. Make me happy, and I shall again be virtuous.
Much like Jean-Jacques Rousseau's "natural man," who begins life innocently, the creature has been harmed by exposure to the corrupted human civilization which creates inequality and unnatural desires such as hatred, jealousy, and envy.
