Exactly right? It's like the author is almost as bad as writing himself into a corner as Kishimoto-
Oh fuck Griffith is a God now- how do we take him out?
In the next Arc Kratos trains Guts on how to kill gods and get his mojo back.
Plus, we all know the only way to un-cuck yourself is to sodomize the cucker and then murder him- so I think Guts is working towards that
