Answer:
Frankenstein's abandonment of his creation immediately after it receives life.
Explanation:
In the book, we learn that Dr. Frankenstein was obsessed with the creation of life. He believed that he was powerful and intelligent enough to be able to create life out of dead matter. However, when he is able to do so, he is horrified by the creature he created, and abandons it.
The creature, however, develops needs that resemble those of humans, and becomes desperate for love and appreciation. Eventually, the fact that his creator abandoned him leads the monster to develop extremely negative feelings towards all humans.
