“Natural Born Killers” is more inspired by Charles Starkweather and Caril Ann Fugate’s little cross-state murder spree. And yes, I think Caril Ann certainly had a hand in at least one of those homicides, despite her denials.
There are NO "natural born killers." Killers are produced by people who sell their souls to Satan.
If you want to read about how ONE was PRODUCED, read about Andrei Romanovich Chikatilo (Russian: Андрей Романович Чикатило, Ukrainian: Андрій Романович Чикатило; 16 October 1936 – 14 February 1994).
He was a bed wetter and his mother beat him relentlessly, throughout the day, all of his young life. His father did/said nothing.
He was a Soviet serial killer, nicknamed the Butcher of Rostov, the Red Ripper, and the Rostov Ripper, who committed the sexual assault, murder and mutilation of a minimum of 52 women and children between 1978 and 1990 in the Russian SFSR, the Ukrainian SSR and the Uzbek SSR. Chikatilo confessed to a total of 56 murders and was tried for 53 of these killings in April 1992. He was convicted and sentenced to death for 52 of these murders in October 1992 and subsequently executed in February 1994.
Chikatilo was known by such titles as the Rostov Ripper and the Butcher of Rostov because the majority of his murders were committed in the Rostov Oblast of the Russian SFSR.
