What happens when we try to tamper with nature? In both stories, monsters are created by artificial means, and the consequences are not good, are they? No one in either story sets out to create a monster, certainly, but look at what happens in each case. In both stories, the attempt to manipulate nature is done through "science," and the "scientists" have not considered the possible outcomes to tampering with nature and have disregarded the ethics of the situation. This theme, of mankind trying to improve on nature, is both ancient and new. As we speak, scientists must consider the ethical and practical consequences of cloning, stem cell use, and medications that can alter the brain. Both stories grapple with these issues in a way that makes a strong point about this theme.
