Is Frankenstein deserving of its subtitle?

 The Prometheus story is about the titular Prometheus stealing fire from the gods, and teaching humanity how to create fire and civilization. For this, Zeus punished him, even though Prometheus’s intentions were benevolent. With that said, is it similar enough to Mary Shelley’s novel for Frankenstein’s subtitle to reference it? And are there similarities to Serizawa’s story in Godzilla? In Frankenstein, Victor was motivated to create the monster by pure ambition, wanting to make the discovery without thinking about the potential consequences, and ultimately, his actions directly backfire on him as his neglect of his creation due to its unsettling appearance lead it to kill his brother, his fiancée/adopted sister, and because of Victor chasing after him in the arctic, Victor himself, followed by the monster burning himself alive to eliminate his remains so nobody like Victor can try and recreate the experiment with zero foresight. The similarities between Victor and Prometheus are limited to going against God and being punished for it, but while Prometheus wanted the best for humanity, but Victor wasn’t thinking about the outcome, he only thought about himself, and ran from consequences. Prometheus’s story is actually more like Serizawa’s. Serizawa created the oxygen destroyer, but he knew that humanity wasn’t ready for it yet, so he worked on it in secret, so that one day, when humanity isn’t itching to destroy itself, he can reveal it, and use it to generate energy to power the world, but when he was forced to reveal it to stop Godzilla, he knew the world would force him to make weapons out of the oxygen destroyer, so he destroyed his research and died with the king of the monsters. He created something that could benefit humanity, but circumstances lead to his punishment for his knowledge. Much more analogous to Prometheus in my opinion.
