What does the creature insist about his own nature What changed his nature?

The creature in Mary Shelley's "Frankenstein" insists that he is not inherently evil; rather, he is a reflection of the treatment he receives from society and his creator, Victor Frankenstein. Initially, he seeks companionship and understanding, but the rejection and fear he encounters from humans lead to his feelings of anger and vengeance. This transformation from innocence to bitterness highlights how external influences can profoundly alter one's nature. Ultimately, he believes that it is the lack of love and acceptance that corrupts him, not an intrinsic malevolence.
