What would be a good thesis statement about revenge and the price of revenge?
This is a great question, as revenge might seem good, but in the long run it really does hurt everything and everyone. In other words, there is always collateral damage. This is why Confucius said these very wise words:
“Before you embark on a journey of revenge, dig two graves.”
Here is an illustration of this thesis. Arguably the best example of this point comes from the book The Count of Monte Cristo. In this book, Edmond Dantés is framed for a crime that he did not commit. For this reason he finds himself in prison. Needless to say, he escapes and begins to seek revenge. He is successful. Careful planning and an endless supply of money makes all of this possible.
However, along the way, there are unintended consequences. Other people, innocent people, get harmed. For example, the innocent child Eduard is killed in the process. Edmond realizes this and feels contrition.
I leave you with words from Abbé Faria: "I regret having helped you in your investigation and said what I did to you." When Dantés asks what he means, Faria replies, "Because I have insinuated a feeling into your heart that was not previously there: the desire for revenge." Abbé Faria, a religious man, knows that revenge is never the solution, not only because humans are imperfect in their justice, but also because God says that revenge is his prerogative.
If you are talking about in general, then I would say that "Despite one's goals for revenge, one only makes things worse for themselves." I say this from personal experience. Everything I try to get revenge for something that someone does to me, it ends up backfiring, and I embarrass myself.
The only other thing that I can think of is that you are relating about a book. From the top of my mind, I can only think of The Scarlet Letter, for which I would say that "revenge destroys both the seeker and victim."
One supporting example for this is when Hawthorne depicts Chillingworth's first attempts to torture Dimmesdale. This shows Chillingworth's revenge, who eventually is compared later in the book to Satan. Dimmesdale, the victim, dies in the end of the novel, which also shows his destruction and downfall.
I hope this gives you a thorough answer to your question.
