What personality trait most likely leads to victor's downfall

I believe that the most fitting answer for this question would be Victor's curiosity and thirst for knowledge. Although this is typically seen as a positive characteristic, it ends up consuming Victor and contributing to his downfall. It leads to him creating his monster, which ultimately destroys him in the end. Hope this helps.
