@Whakatewhinau okay, but then how does he stop someone from killing him? From what it's showed and said, he can't control nor feel his body while inside the prison, so if someone comes and cut his neck he can't do anything, I mean yes he could break free from the prison, but that doesn't mean he knows who could be in front of him if he's in the prison
And looking back, when it shows him escaping the actual prison and not the bug, he pretty much had already left the mental prison and was only waiting to kill the warden, meaning that at least before that he can't control his body, nor interact with the exterior world
