Summary
Analysis
Victor despairs that his good intentions have resulted in such horror. Soon the Frankensteins go to their vacation home in Belrive to escape the bad memories of what's happened. Yet Victor still has thoughts of suicide and begins to desire revenge against the monster.
Victor's response to the monster's betrayal of him mirrors the monster's response to Victor's betrayal: both isolate themselves in nature and seek revenge.
A while later Victor decides to travel to Chamonix, France, hoping the trip will provide relief from his "ephemeral, because human, sorrows." Along the way he gazes at waterfalls and the towering Mont Blanc. At times the sights remind him of happier times, but never for long.
A sentiment typical of Romantic literature: human concerns are "ephemeral," or short lived, whereas Nature is as enduring as God.
