What does Mary Shelley say about science and morality in Frankenstein???

That we can't take on the role of God. Victor Frankenstein tried to create life from death and the consequences were dreadful. He tried to defy the natural order. Sometimes scientific research and success has serious implications. (atomic bomb and Einstein).When the monster asks him to create a companion for him, though, Victor feels it's not morally right, even though that would save his family.
