A good revenge is sweet when cold served

Choice is yours. Bad? Good? Worse? 

Revenge is a form of justice enacted in the absence or defiance of the norms of formal law and jurisprudence. Often, revenge is defined as being a harmful action against a person or group in response to a grievance, be it real or perceived. It is used to punish a wrong by going outside the law. Francis Bacon described revenge as a kind of "wild justice" that "does... offend the law [and] putteth the law out of office." Primitive justice or retributive justice is often differentiated from more formal and refined forms of justice such as distributive justice and divine judgment.

Vengeful behavior has been found across a majority of human societies. Some societies encourage vengeful behavior, which is called a feud. These societies usually regard the honor of individuals and groups as of central importance. Thus, while protecting of his reputation an avenger feels as if he restores the previous state of dignity and justice. 

According to Michael Ignatieff, "Revenge is a profound moral desire to keep faith with the dead, to honor their memory by taking up their cause where they left off". Thus, honor may become a heritage that passes from generation to generation. Whenever it is compromised, the affected family or community members might feel compelled to retaliate against an offender to restore the initial "balance of honor" that preceded the perceived injury. This cycle of honor might expand by bringing the family members and then the entire community of the new victim into the brand-new cycle of revenge that may pervade generations.

The popular expression "revenge is a dish best served cold" suggests that revenge is more satisfying if enacted when unexpected or long feared, inverting traditional civilized revulsion toward "cold-blooded" violence.

"Before you embark on a journey of revenge, dig two graves": 

Confucius stated that, “Before you embark on a journey of revenge, dig two graves.” ... To me, it means that if you're seeking a revenge, you might as well destroy, not only the other person or persons, but also yourself.
