In Emily St. John Mandel's novel "Station Eleven," the theme of regret plays a pivotal role in shaping the characters' experiences. The protagonist reflects on how age influences one's sense of remorse and missed opportunities. At twenty-one, life is often filled with possibilities, whereas by fifty-one, the accumulation of regrets can weigh heavily on a person. This contrast emphasizes the emotional journey that individuals undergo as they navigate through life’s choices and the accompanying consequences.

As characters grapple with their pasts, the narrative illustrates how regret can lead to profound introspection and a reassessment of priorities. The acknowledgment of regret serves as a catalyst for growth and change, suggesting that while such feelings can be burdensome, they also have the potential to inspire resilience and hope. Ultimately, the exploration of regret becomes a crucial aspect of the human experience in the story.
