People will lie, make false claims in court, destroy property, try to sleep with their ex to ruin the ex's current relationship, keep a man from his children, spread rumors, post blogs on Myspace about a person, or post pics of them online and use various other methods to get revenge...I know people that have done some of these things. When someone does you wrong, retaliation just seems like a good idea.
The Bride's personal vendetta in the movie "Kill Bill" displayed revenge in the most glorifying way that I've ever seen it displayed. She goes on a revenge fueled quest to kill every member of an assassination team that betrayed her. The end of volume two is the best part. She kills Bill and unites with her daughter. It's beautiful, but it's a movie. In real life, there's this thing called Karma.
Karma is that little thing that comes back to bite us in the ass when we do something wrong. Like bad seeds we've sown, it always reaps it's little head.
Karma Definition: the force generated by a person's actions held in Hinduism and Buddhism to perpetuate transmigration and in its ethical consequences to determine the nature of the person's next existence
Law of Karma: All living creatures are responsible for their karma. The concept of karma was first developed in India by non-Aryan people whose spiritual ideas greatly influenced later Indian religious thought. Buddhism and Jainism are continuations of this tradition. Basically, what one does in the past affects one's future: performing good deeds will result in good effects and performing bad deeds will result in bad effects.
