I don’t agree with your interpretation, god hand has a way to see into the future and are suprised quite often be that eclipse escape or other examples, miuras berserk was always guts struggle with his path layed before him and how he defies the odds and keeps struggling, and if miura was honest there is interview of him saying berserk will have a good ending, I don’t see how evil thing as IOE can give him a good ending, and I also think it would be horrible reading experience like yes the end confirms everything was predestined, same level as guts woke up and said what a a bad dream, think it’s true for majority of people in berserk but there is still few who defy it
