For generations now, people have been correcting each other. Frankenstein is not the name of the monster, it's the name of the mad scientist who created the monster! But then again, a more thoughtful take on that would be that the real monster of the story is the mad scientist, Dr. Frankenstein.
In Mary Shelley's original novel, Frankenstein isn't even a doctor. But he is a scientist, whether mad or evil or both. It takes a lot of hubris to imagine one can reanimate dead body parts, essentially making a man. The creature itself is the victim, not only of being reanimated without consent, but being seen as a monster, undeserving of love. The novel delves much deeper into the ethics of science and the danger of playing God. Monstrum, from PBS, explains some of the deeper themes addressed in the original 1818 novel Frankenstein; or, The Modern Prometheus.
