One of the main draws of the Saw franchise is how twisted the games that John Kramer (Tobin Bell) play end up being. No matter what, while many think he's a hero, his role as Jigsaw is as sadistic as they come. It doesn't matter if he touts himself as a vigilante or "life coach" helping test people and put them back on track; his games are all about blood and gore.
