Notable Moment in Mary Shelley's Frankenstein

While reading Mary Shelley's Frankenstein, I became aware of the main character's sound judgement and overall knowledge to be astounding. Whether in science, humanities, or mathematics, Victor seemed all together the brightest character in the novel, with intuition abound. That is largely why I found his failure to comprehend his creation's threat to essentially kill Victor's bride-to-be, Elizabeth, so confounding. I assumed that Victor would have seen the creature's intentions immediately and have carried out a different set of actions instead of playing directly into his nemesis's hand, despite how painful it may have been for Elizabeth. After thinking it over, I came to the realization that his lapse of judgement could only have occurred due to the rapid decreasing stability of his mind and the guilt that weighed upon him for the deaths of the first three victims. I believe Shelley tried to prove the point that under extreme duress, even the most secure and brilliant minds can become unhinged.
