10 Horror Movies Where The Victim Is More Dangerous Than The Villain

While the argument is there that 2010's I Saw The Devil is more of a thriller than a horror, this writer would beg to differ. The horrifyingly intimate subject matter of the film is arguably infinitely scarier than a few jump scares and squirts of corn syrup; a man made a victim by the murder of his pregant fiancee, who soon reveals that he is more terrifying than any killer.

The Korean masterpiece tells the tale of a serial killer who unwittingly dispatches a young woman, unaware that her betrothed, a Korean intelligence agent, will swear undying revenge on him. Soo-Hyun, the aforementioned agent, soon discovers who the killer, Kyung-chul, is but does not dispatch him, choosing to implant him with a GPS device and torture his twisted way of living.

The plot backfires on Soo-Hyun, as the killer deduces his identity and brutally murders his father and sister-in-law-to-be in retaliation. However, Soo-Hyun eventually gets his hands on Kyung-chul and enacts his revenge in the most chilling fashion possible; strapping the murderer into a makeshift guillotine that is triggered by Kyung-chul's family opening the door to the room in which he is imprisoned, beheading the murderer at his "most painful moment" and sending his family to therapy for the remainder of their lives.

It's hard to imagine a man who responds to the death of his fiancee by enacting a campaign of psychological terror against a serial killer, but once one does, it is clear he is not to be trifled with.
