If the history of humanity were the clinical case history of a single human being, the diagnosis would have to be: chronic paranoid delusions, a pathological propensity to commit murder and acts of extreme violence and cruelty against his perceived "enemies"—his own unconsciousness projected outward. Criminally insane, with a few brief lucid intervals.
