Frankenstein how is revenge shown to be self-destructive?

In Mary Shelley's novel "Frankenstein," revenge is portrayed as self-destructive through the actions and consequences experienced by both Victor Frankenstein and the creature he creates. Victor's initial desire for revenge against the creature, after it kills his loved ones, consumes him and ultimately leads to his own downfall. He becomes consumed by guilt and obsession, leading to his physical and mental deterioration.

Similarly, the creature seeks revenge against Victor for creating him and then abandoning him. However, after realizing the futility and emptiness of his actions, the creature also suffers from isolation and despair, ultimately leading to self-destructive behavior.

Overall, the theme of revenge in "Frankenstein" serves as a cautionary tale about the destructive nature of seeking vengeance and the negative impact it can have on both the perpetrator and the victim. Ultimately, revenge only perpetuates a cycle of violence and suffering, leading to the destruction of all involved.
