Jigsaw (Horror Reboots)

Jigsaw (John Kramer) is the main antagonist of the Saw reboot franchise. He is a serial killer bent on the intention of teaching his victims to appreciate their lives and every single moment of their life by placing them in his deadly traps and twisted games, and the only way to escape his gruesome tests is often to force themselves through excruciating physical or psychological torture.

Personality
John Kramer was a hardworking man devoted to his family and his work to help those who are disadvantaged in society. He had strong convictions and even before his transformation to Jigsaw, he believed that only the knowledge of impending death could show if a human was actually willing to fight for their life and survive. He was also spiritual and interested in esoterics such as Chinese astrology.

However after tragedy struck him, John Kramer became depressed and attempted suicide but survived, causing him to realize that he actually wanted to live, and therefore, he decided to spend the rest of his life teaching other people the appreciation of their lives and the lives of the people around them.

When he became Jigsaw, he started to test peoples' will to survive by placing them in terrifying and deadly traps. Despite the immense brutality of his games, John took no pleasure from the suffering of his victims but thought it was necessary to make them cherish their lives. Throughout his murder series, he always tried to keep an emotional distance between him and his work and did not let his own feelings affect his mission. John never doubted that his mission was necessary and that it was the right thing to do. He also saw it as a way of bringing justice to his victims for things that they did to themselves and others.
