Combined with his status as a Base-Breaking Character, his detractors are starting to feel he has really overstayed his welcome. Security Breach would then establish an entirely new set of characters (including a new antagonist) that fans felt were quite interesting, only for William to appear yet again in the ending despite having very little presence in the game otherwise. While people were fine with his return in Pizzeria Simulator, many were left disappointed after VR and Fazbear's Fright seemingly established a Happy Ending Override that implied he survived.

Arc Fatigue: A good portion of the fanbase is starting to get tired of William Afton's Joker Immunity.

This could be a reason why in the Fake Ending, he may have brought Ennard home with him, since they might have his sister in there.

In the Private Room Ennard implies that Eggs wants to see 'her' again, most likely referring to his dead sister who was eaten by Baby, and believes she's still alive as Baby and thus, wants to keep her as near him as possible.

Are they genuinely evil, or just stupid? Or both?

The management, and Fazbear Entertainment as a whole.

The Phone Guy simply faked his death and recorded backwards audio after the fourth day up until he retired. In this case, the guard simply faints from fear if caught and dreams of being mangled.

One interpretation of the Phone Guy is that he's lying about the sentient robots being murderous to screw with your head.

Are they simply machines with malfunctioning programming, or are they corrupted by being haunted? Likewise, there is debate over whether or not they're truly malevolent or if they do genuinely believe you need 'help' back into your costume. Since people with disabilities often have a harder time finding work and additionally tend to have higher medical expenses, if he is disabled that might explain why he's willing to stay.

Adding to the first possible explanation, some people have theorized Mike Schmidt might be disabled, since he is unable to move from his seat, and is paid less than minimum wage (even for his day).

Is it because he is so desperate for money? Does he not want another poor sap to take his nightmarish job? Is he under contract that prevents him for simply quitting? Does he not believe that he's really in danger? Is he trying to figure out what's going on? Is he some kind of Nightmare Fetishist who finds his job thrilling? Or is he a literal Nightmare Fetishist?

The reasons behind Mike coming back to Freddy's.
