17. Prince Sado Became a Monster Feared Throughout Korea
Prince Sado was a troubled young man, given to extremely violent and erratic mood swings. One day, he would behave with such decorum, dignity, and probity, that he was all that his father had ever wanted in a son and heir. The next, he would undergo a transformation, and give free rein to violate outbursts during which he would turn rapist and murderer. Historians are unsure just what exactly ailed him, but he was clearly mentally unstable. Today, many think that he was schizophrenic.
Although alcohol was forbidden at court, the Crown Prince routinely downed copious amounts of wine and spirits, and became a raging alcoholic. When a depressive mood fell upon him, murdering servants brought Sado relief. On many a day, several dead bodies were carried out of the palace. He also enjoyed raping court ladies. His depravities extended to his own family: after murdering his concubine, he started sexually harassing his own sister. That behavior made Sado widely feared throughout Korea as a serial rapist, serial killer, and all-around dangerous psychopath.
