[ WP ] The Natural-Born-Killer gene was decisively phased out of the global gene pool as soon as it was discovered , launching humanity into a new era of peace . A century has passed since then , but troubling events have prompted a world-wide search for individuals possessing the elusive gene ...

Three billion. Well three billion, two hundred and seven million, four hundred and two thousand, and one hundred and seven base pairs to be exact. The entire human genome mapped by hundreds of high tech computers and meticulously studied by thousands of scientists for the past hundred years to the point of perfection. First, pharmaceutical companies manufactured high end biosimilar products, medication engineered to directly treat any disease at the genetic level. Antibiotics, antidepressants, antihistamines... All of these drugs made obsolete. No more diseases, no more infections, and no more threats to humanity. 
 
 Except ourselves. Nations kept starting wars, criminals continued victimizing the innocent, and people died every day. No drug could stop a hollow point bullet from tearing someone's head off nor allow an individual to survive the lethal radius of an explosion. The war of 2025 alone claimed 33 million lives. Then scientists began to realize the obvious solution, the genome. If scientists could alter the human genome to prevent disease, then why could n't they alter the genome to prevent violence? 
 
 NBKI-23. Short for `` Natural Born Killer'' discovered by Dr. James Locke in 2031, an avid Michael Jordan fan. With government approval and funding, the project to develop a drug that could target NBKI-23 received high priority. After two years of extensive trials on mice and monkeys, scientists prepared for human trials. Volunteers, patients with uncontrollable anger issues, in small numbers received the first doses. The results exceeded all expectations. Every single subject no longer exhibited outward signs of anger, distress, or irritation towards any negative stimuli. A one hundred percent success rate. 
 
 Next, the government offered reduced sentences to prisoners willing to participate in the NBKI-23 stage II trials. Again, out of thousands of violent prisoners, a one hundred percent success rate. In stage III trials, all hospitals offered admitted patients a chance to participate in the study with a government incentive. After tens of thousands of injections, hospitals reported a drastic decrease in events requiring security over a period of six months. In 2039, the government fast-tracked the medication to be released within a year, and legislation passed requiring all doctors and pharmacists to offer the shot to all patients. 
 
 Crime rates started to drop drastically. Homicide became a rarity. Within a few years, nearly 90 % of the population received the injection.Soon, chemists developed a nebulized version for easy administration in other countries. Organizations funded outreach missions to less fortunate regions in the world. An era of peace loomed on the horizon.
