"abhorred monster! fiend that thou art! the tortures of hell are too mild a vengeance for thy crimes. wretched devil! you reproach me with your creation; come on, then, that i may extinguish the spark which i so negligently bestowed." my rage was without bounds; i sprang on him, impelled by all the feelings which can arm one being against the existence of another. he easily eluded me, and said— "be calm! i entreat you to hear me, before you give vent to your hatred on my devoted head. have i not suffered enough that you seek to increase my misery? life, although it may only be an accumulation of anguish, is dear to me, and i will defend it. remember, thou hast made me more powerful than thyself; my height is superior to thine; my joints more supple. but i will not be tempted to set myself in opposition to thee. 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. i was benevolent and good; misery made me a fiend. make me happy, and i shall again be virtuous."
what do you believe the allusion to the “fallen angel” means in this passage?
