Final answer:
Victor Frankenstein isolates himself because of the guilt and horror he feels about the creature he created, leading him to a life of misery and regret.
Step-by-step explanation:
Victor Frankenstein, the protagonist in Mary Shelley's novel Frankenstein, feels he can't be with people because he is overcome with guilt and horror regarding the creature he has created. He is isolated by his own sense of responsibility for the monster's actions and the fear of being discovered. Victor expresses a complex opinion about his creation; he is horrified by its physical appearance and repulsed by it, leading to immediate regret and disgust after bringing it to life. This internal battle contributes to his inability to connect with others and his suffering. Shelley's work does not provide a definitive answer as to why Victor reacts this way, but instead invites readers to explore the complexities of his character and the ethical implications of his scientific pursuits.
