Yoo Young-chul's murder spree was fueled by a deep-seated hatred for women and the wealthy. After a life marked by a criminal record, a broken family, and imprisonment, he meticulously planned his attacks. Operating primarily in Seoul, he would pose as a police officer or a suitor to gain entry to the homes of the rich elderly, binding, bludgeoning, and stabbing them. His most gruesome victim count, however, came from his targeting of women from massage parlors. After gaining their trust, he would murder them in cheap motels, often dismembering and disposing of their bodies in the mountains, only to return to the same parlors for a new target.

He needs a sinner to help him. This isn't historically accurate, but it is emotionally and thematically resonant. It asks us: what kind of monster does it take to catch a monster?
