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.
