He was sick. Sick of all of it. The sickness inside him. The tricycle from his childhood was supposed to be relinquished to his son once he grew old enough to ride it, but that day would never come, for his unborn child, who would have been his firstborn, was not to belong to this world. Life did not mean for John Kramer not to have a son, a child of his blood to carry on his name and lineage. He started off as an adoring and loving husband to his wife, but the role of a father was not to be his destiny. Instead, he would become known as a killer, a monster in some people's eyes. The world didn't care about him, so why should he care about everyone else, especially when people didn't have any respect for those other than themselves, who cared about anyone but themselves?
Something needed to be done, even if it took a little bloodshed for the scum of this world to open their eyes and see the error of their ways, to show appreciation for the life given to them, lives they didn't deserve. Not all people were bad, but a lot of them weren't exactly good, either. All John Kramer wanted was to be a good husband and father, as he envisioned himself to be, but fate did not recognize his wishes for a simple life with his family. Instead, it chewed him up and spat him back out like some unwanted substance.
John Kramer never meant to fall out of love with Jill Tuck. They both knew their marriage was over the moment they lost Gideon, the unfortunate soul who never had a chance to live a full life. John never meant for the marriage to end like this, and as if things weren't bad enough already, it only got worse for him when he went to the hospital weeks later and was told he had only a few months to live.
Unaccepting of letting the sickness eat away at him from the inside, John decided he would take matters into his own hands, choosing to die another way by driving himself off the road, hoping to end his life in a less painful manner. What he didn't count on was waking up and finding himself still alive inside the car, impaled and bleeding. His survival instincts kicked in right away, filling him with a newfound desire to live, even if he was still doomed to die from cancer. If God or some other deity or unforeseen force of nature had granted him a second chance to live, then John Kramer decided that he would dedicate the rest of his limited amount of time left on this planet to testing his newfound outlook on those who felt the same way he did, the way he used to feel.
All he ever wanted was to have a normal life, but that was not to be his destiny. Fate had something much more meaningful for John Kramer to uphold, something of a dark and sinister nature. Controversial, to say the least. Above all, not everything he did was unmerciful, so long as the people who would later become involved in his games saw the true meaning behind his traps: finding a new appreciation for life.
