The thing about choices in The Magnus Archives and how they don’t matter is that the opposite is true for Jon. In the actual narrative. Every choice Jon made was the wrong one that brought him closer to being inhuman and hurt innocent people and ended the world. This is text in the story. This is the view point being shown by the other protagonists/antagonists. Jon didn’t have to shake Jude’s hand. Jon didn’t have to ask Mike Crew about his scar. Jon didn’t have to read a Guest For Mr. Spider. He was one of an innumerable amount of puppets of the Web that would’ve ended the world. He could’ve just. Not. So I’m sorry if I want to have a more charitable view of a FICTIONAL character who LITERALLY had no agency within the text of the story and not just because it was a story being told in the first place.
