Imagine not getting caught for any of your crimes because
A. You're good at hiding it, and
B. You just get rid of anyone who CAN find out
I got an interesting FNAF theory involving William Afton's wife. What if William killed his own wife when she found out that he was the one responsible for the murders of the seven missing children? Like for instance: when William Afton killed the children he arrived home just for his wife to come in with a newspaper talking about the murder and before she could call police William killed her so that there would be nobody to come after him and take him to justice.
