Well, I wouldn't use those words exactly. Rather than annoying, I'd say I'd be frustrating to the reader, but let me go back
At times like this, an I'm it's been mentioned to you before, you need to really consider why a person giving you that piece of advice or bring up opposition to point or decision you've made, and also look at the grander point of what they've made rather than focusing on a specific detail. You're focusing on me saying it would be better to having where Nobody is ignorant, but you're missing the following paragraph where I explain myself. But let me further explain... by asking you more questions.
Is your story character driven? If it is, then Nobody being well aware of the conflict and not doing anything about it doesn’t make that much sense for his character. In your most recent draft that I've read, there is a conflict with the witches at the end and when Heiroe is in a tough spot, Nobody is willing to throw himself into battle to help him, despite it being a fight with the people that he escaped from. Why would he jump in for a stranger unless he knew that he wouldn't be recaptured by the witches? Oh wait, he doesn't know that, but who does know that? The author, you do. And that's where the frustration will come in for the reader. Because it stops being about why a character made that decision and more about why the author wrote the character that way.
If your story is character driven, character motivations need to line up with character actions. In the same chapter Nobody is introduced to be running away from thr witches, he makes the active choice to fight them. If he's capable of fighting them and defeating some, why was he running away from them? Because he needed to run into Heiroe? One, that's not a good enough reason, and two, if Nobody can defend himself, is aware of his powers and of the conflict between the zones, and that there is a chosen one, why hasn't he made any attempts to escape thr witches and defeat the dark lord before?
Look, you may know the answer to those questions, but the reader doesn't. And you need to be considerate of that.
