Pigsaw story

When John Kramer, better known as Jigsaw, planned for his son to be born during the Chinese Zodiac's Year of the Pig, he wanted it to represent fertility and rebirth; a new beginning for him and his wife, and the start of a charmed life for his son. But that plan was shattered on the night that a junkie broke into his wife's clinic, hoping to score.
After this event resulted in the death of his unborn son, John finally caught up with the junkie, making him his first test subject, and The Pig was changed forever too. It became a representation of the disease that was rotting John from the inside, a reminder that we are just meat unless we elevate ourselves by our actions, by grasping life from the jaws of death. The Pig became a vessel, an agent of Jigsaw, conveying the subjects to their test. For some of those who emerged victorious, The Pig could still be a rebirth, into their new lives as apprentices, even disciples, of Jigsaw.
That was the case for Amanda Young, a troubled soul, whose life had been a catalogue of harm, both to herself and those around her. That changed when she faced, and bested, Jigsaw's test. Deciding her life was worth something, she became devoted to Jigsaw's cause, ready to take over when cancer consumed him.
But she became more dependent on John, her anguish at his impending death combining with a belief that their test subjects weren't capable of saving themselves, of being reborn in the crucible of the games.
Seeing this, John presented her with another game, another chance to save herself, but Amanda let her rage and jealousy rule her actions. She failed the test and took a bullet as a consequence.
