Frankenstein
"I feel as if I could die in peace, now that my innocence is acknowledged
by you, dear lady, and your cousin"
Justine and Frankenstein's monster both desire the same thing after being outcasted and isolated from society.
Justine only needed two people to believe her innocence to leave the world contentedly. the monster simply requests a creature of the same kind as him from Frankenstein to allow him to live peacefully away from society.
This displays humanity's need for companionship to keep them sane, even with just a few. This stresses the romantic movement's emphasis on human connection and emotion for one to truly experience life itself.
"the apple was already eaten, and the angel's arm bared to drive me from all hope"
This quote alludes to the story of Adam and Eve in the Book of Genesis. "The apple" Frankenstein had eaten was the creation of his monster. By artificially creating life, he pushed natural boundaries as a human and obtained forbidden knowledge, similar to Adam and Eve eating the forbidden fruit and sinning against God.
"The angel's arm" exiled him from what would be considered his paradise, which is his relationship to his loved ones, and self-fulfillment through nature and life, just as Adam and Eve were banished from the Garden of Eden. Losing his romantic ideals and connections to others, Frankenstein is left in despair and hopelessness because this sin.
His downfall stresses the dangers of unchecked ambition and defying natural order and boundaries.
