Just strange that a WWII vet would go off the deep end like that.
Statistically, anyone of his age would be a WWII vet, be it a saint or a demonic freak like this guy. Being a vet doesn’t automatically give you a halo, albeit, normally they are the best of the best, but pretty much every healthy male from 17-40 during that time was conscripted so there would by sheer numbers, be some bad apples in there.
