The novel Frankenstein, by Mary Shelley, follows one of the main characters, Victor Frankenstein, and the events that lead up to his creation of a monster, as well as the madness that occurs as a result of to his creation. Through the turn of events that take place in this novel, the reader is exposed to what makes one human and what makes someone a monster. It is clear that Frankenstein being a human being and the monster he created switch roles by the end of the novel due to the situations in which they land. Frankenstein's creation, though physically appearing to be a monster, ironically develops characteristics and qualities resembling those of a human being. The monster is able to sympathize, empathize, crave knowledge, feel lonely, become depressed, want revenge and, like humans, commit unspeakable crimes because of the trauma he is exposed to and left to deal with alone the minute Frankenstein abandons him. In the same token, as the reader continues to learn more about Victor, it is easily noted that he embodies a typical monster. He is incredibly selfish, has no sense of responsibility, does not care for consequences, puts himself before others, does not care about how his actions will negatively affects others, cannot own up to the things he does, and blames people for his wrongdoings. .
While humans can be selfish and sometimes lack responsibility, Frankenstein's egotistical qualities are what cause his inability to reason, justifying his label as a monster. Out of desperation for fame and greatness, Frankenstein creates a monster that later in the story is responsible for the majority of the tragic events that take place. Completely consumed in his idea to create life and the possibilities of notoriety as a scientist, he disregards any of the possible dangers that could come out of his experiment if not successful. Frankenstein says ignorantly, "A new species would bless me as its creator and source; many happy and excellent natures would owe their being to me.
