Characterization
The producers of the Saw films have fought to differentiate the Jigsaw Killer from other horror film killers. Darren Lynn Bousman, the director of Saw II, III and IV, has stated on the character's role "He's not Jason or Freddy. He's not even Hannibal Lecter. He's a person with extreme beliefs and he really thinks he's making a difference. He's a vigilante if anything. He thinks he's making a difference." Tobin Bell, the actor who plays Jigsaw, describes his character's role as being more of a scientist or engineer and "he thinks very specifically and very pragmatically". About Jigsaw's games being detail oriented, Bell said: "My sense is that Jigsaw is so detail oriented that I think he thinks in terms of worst case scenario. I think he’s a very good judge of character, so his sense that, for example, that Detective Matthews was going to play right into his trap, which he did, was right on. Now, it seems to me that he's always got a second plan in place. And there's probably been a number of second plans. I mean, we've only seen three movies. Maybe there are six more somewhere where he failed, where something didn't play out". Speaking about playing the character, Bell stated that "ou have to think of someone like Jigsaw from a very specific point of view. He doesn't view himself as some kind of diabolical psychotic. You know there's a little bit of evil in everyone. It just gets carried further. Most of us have some sort of moral fiber that restricts that. Some framework. And then others because of their lives and what happens to them, the thing develops in some other way."
Bousman mentioned that Saw III was intended to contain a scene in which Jigsaw showed remorse for his actions after seeing the results of his legacy:
"For the first time, we actually see him break down and cry. Imagine your entire life's work. You're on your deathbed. You know there's nothing else you can do and here's how you'll be remembered: as a killer, as a murderer. Not as someone who helped people. Not as someone who changed lives. Someone who took away lives. The one thing he didn't want to be and, as he's on his deathbed, he's realizing this."
As a result of his cancer and a failed suicide attempt, John decided to dedicate the rest of his life to teaching people to appreciate their own lives. The producers of Saw III and director Darren Lynn Bousman see Jigsaw, not as a serial killer, but a "scientist" who is determined to initiate the survival instinct in his "subjects", believing that humanity no longer uses its instinct of survival.
While the character's discovery that he has cancer is acknowledged to be the "final straw" that drove him to his actions, Bell has stated in an interview that "His terminal cancer is one of the elements of his life but he's as angry over the fact the world is going to hell in handbasket because it's no longer the survival of the fittest; it's the survival of the mediocre. That drives him as much as anything else. He doesn't just talk about his frustrations, he does something about them, and he puts himself on the line. His cancer was about one element in about 130 elements that caused him to create the world that he's created."
Jigsaw is depicted in the Saw films as being extremely intelligent in the areas relevant to his actions. In Saw: Rebirth he is depicted doing extensive study in multiple fields to gain knowledge for designing his tests, and recurring director Bousman himself has described Jigsaw as being "extremely educated" in an interview.
