"I wanna play a game with you"

https://en.wikipedia.org/wiki/Jigsaw_(Saw_character)

John Kramer (colloquial: "The Jigsaw Killer") is a fictional character and the main antagonist of the Saw franchise. Jigsaw made his debut in the first film of the series, Saw, and appears in all subsequent sequels, with the exception of Spiral. He is portrayed by American actor Tobin Bell.

In the series' narrative, John is a former civil engineer dying from an inoperable frontal lobe tumor that had developed from colon cancer. After a suicide attempt, John found a new appreciation for his life and dedicated the rest of his life to inspiring the same appreciation in others by testing their will to live. His methods include forcing his subjects through deadly scenarios, which he refers to as "games" or "tests", in which they are forced to inflict pain upon themselves or others in order to escape. These tests are typically symbolic of what Jigsaw perceives as a flaw in each person's moral character or life. The Jigsaw name was given to him by the media for his practice of cutting a puzzle piece-shaped chunk of flesh from those who fail.
