A serial killer who doesn’t kill. That’s the intrigue at the heart of the Saw films. Instead, Jigsaw’s victims are placed within a game. A game in which you may face great pain or even the loss of a limb, but in which it is always possible to survive. Why? Because Jigsaw is dying of cancer, and with that knowledge weighing him down he looks at the world and sees humanity wasting their lives. He wants them to understand how incredible it is to be alive.
