How did william afton kill his victims A third theory is that Afton uses the "bite of '87" as a method of killing his victims. In the second game, it is revealed that a child was bitten in half by an animatronic, and it is heavily implied that Afton was responsible. This theory suggests that Afton used the animatronic's sharp teeth to kill his victims, possibly by luring them into a room with the animatronic and then activating it. A fourth theory is that Afton uses the "remnant" substance to kill his victims. In the series, remnant is a mysterious substance that is said to have the ability to give life to inanimate objects. It is also said to be able to trap the souls of the dead inside of animatronics. This theory suggests that Afton uses remnant to kill his victims by trapping their souls inside of the animatronics, effectively killing them. A fifth theory is that Afton uses the "agony" of the children to kill them. In the series, agony is a powerful force that is said to be released when a person dies in a state of extreme fear or suffering. This theory suggests that Afton uses the agony of the children to kill them, possibly by luring them into a room with an animatronic and then activating it to scare them to death. In conclusion, while the games never explicitly show how William Afton kills his victims, there are several pieces of evidence and fan theories that suggest possible methods. These include luring the children to a secluded area, using the animatronics to kill them, using the "bite of '87" as a method of killing, using the "remnant" substance to kill them, and using the "agony" of the children to kill them.
