Defining the Worst Criminal
There is no single official ranking of the worst criminal ever. Historians and criminologists instead compare individuals by the scale of harm, number of victims, and global impact of their actions.
Notorious Serial Killers
Some of the most lethal individuals in recorded history include Harold Shipman, a British doctor convicted of murdering at least 15 patients, and Luis Garavito, a Colombian killer who confessed to the murders of over 100 young boys.
Organized Crime and Mass Atrocities
Beyond individual killers, leaders of organized crime and regimes have caused immense suffering. Pablo Escobar, a Colombian drug lord, was responsible for thousands of deaths and widespread violence.
