Theres no use to it all.
The purpose of life is for one to live how they deem suitable to their own wants and desires. When those wants and desires are infriged upon for whatever reason, the natural reaction is to take steps to either resolve the conflict, or punish the cause of the infringement. While this may be a naturally instilled instinct...its pointless. When someones life-situation is infringed upon, and punishment is doled out, it doesnt change or resolve anything.
examples:
- a girl who was 'soft' raped had their rapist physically damaged. 'soft' rape being something like date rape, where it was a known person and physical violence wasnt involved. the individual causing the physical damage to the rapist no longer even talks to the girl.
- a girl who was raped for real, as in her drink drugged, knocked out, then taken to be violently raped by multiple men, where law enforcement absolutely refused to investigate, had the individual who drugged her drink repaid in spades. the karma-bomb that went off in his existence was to such a degree that the person will never be causing unhappiness...or any happiness for that matter...again. the girl no longer talks to the person who introduced the karma experience to the rapist.
- an individual caused a second individual to get fired from their job. the second individual then took steps to have the karma-bomb show how inappropriate their actions were and how displeased they were. during the 'work up' to taking active steps, it was discovered that the first person was an actual, literal whore. as in...sold their orifices to complete strangers for money. not only that, but they were a frequent consumer of various recreational pharmaceuticals, including some of the 'bad' ones. how the fuck do you top that? the universe has already shit upon this person like a herd of elephants using a ground-hogs hole as their favorite latrine.
- a law enforcement individual caused a second individual to have some degree of legal problems. the second individual then called upon the wondrous mysticism of karma, at which point the LE individual had their credentials stripped, literally arrested, disbarred (they were also a practicing lawyer), and as of last check they were working as a para-legal at some shit-house law firm.
- an individual who caused a second individual to have a fairly high degree of strife had an unpleasantly elaborate karma-experience. the first individual was married, with children, and mentally stable. after karma used them as its personal pocket-pussy during a viagra and meth overdose, the individual was single, children in the court-ordered custody of the grandparents, addicted to drugs, literally selling their sexuality for money, mentally defunct to the point police were called to resolve their public displays of psychotic breakdowns ('baker acted' for running into a 7-11 and telling the cashier there was a man underground in the fuel tanks setting bombs and the FBI needs to be called), and several other less significant examples.
there are many, many, other examples, these are just the more extreme ones, but it doesnt change the fact that overall, nothing is changed. if the individuals committing the wrongs hadnt had any reaper-cussions...or had their lives totally and utterly ruined...the mental state of the original person who was wronged stayed the same. no satisfaction. same exact feeling.
