I suppose that spending five years in a warzone would have an affect on a person. Doing so with no discernible, rational philosophy would probably be a sort of personal, self-inflicted hell. I read as much of this account as I could, but the nihilism and naturalism was too much to bear.
It sort of felt like looking at birdshit on the crumbling facade of a post-modern office building made to look like it had been through an earthquake. If you know what I mean.
