Talk about William's strength in game (and also novel one)...William may not have the raw physical power of a bulky bodybuilder or the stamina of someone trained in combat, but his psychological strength is off the charts. He knows how to manipulate, control, and break people mentally before he ever lays a hand on them. That makes him far more dangerous than someone simply relying on physical strength.
Thinking about the idea of William Afton might “comforting” his victims before he kills them is horrific because it shows just how deeply manipulative he can be. In the FNaF novel and extended universe, William Afton’s ability to play the role of the charming, comforting figure just before he kills is utterly chilling. For example, the scene with Officer Dunn isn’t just brutal; it’s drawn-out, with intentional pauses that make the violence feel colder. His calmness during murder shows that he’s not just physically strong but emotionally manipulative. His victims are trapped in the horror of being lulled into false safety before the blade comes down. He broke Dunn’s arm to control him, making him weaker, more vulnerable as he suffocated and finally stabbed him repeatedly; the gentleness of it adds to the horror—there’s no rage. There’s just cold precision. He may whisper reassurances or “calm” his victims (the children) as they panic—letting them believe that he’s not dangerous, only to then rip their world apart with brutal precision. It makes him feel almost godlike in his ability to toy with life and death. Imagine he softly murmuring to his victim, just before they die, almost like he’s reassuring them that it’s all going to be okay. That’s the true horror. The unsettling sweetness in his tone as he delivers cruelty. His ability to comfort victims before he kills them adds layers of cruelty. He doesn’t just overpower them in a primal way; he’s deceptive, methodical, and can lull them into a false sense of safety. This is what makes his violence so insidious, it's not about the physical pain, it’s the calculated calmness in his voice, his ability to speak like it’s just another day while delivering death.
While the image of a "strong man" who relies on aggression can be terrifying, William Afton’s true power lies in how he exerts control. He may not look imposing physically, but when he’s in charge, he can break someone down with just his voice, his gaze, and his calculated moves. There’s a terrifying serenity in the way he operates—he doesn’t need to be violent in the conventional sense because he has the mental and emotional foothold on his victims.
Breaking a limb and suffocating them, with the slow buildup before the final stabbing? That’s terrifying not because it’s physical violence, but because of the methodical cruelty. William isn’t acting in a rage-filled frenzy. He’s cold. He’s careful. It’s all part of the show.
