Well, for every person who denied enjoying it, theres probably another who actually did enjoy it.
People know, inherently, what is absolute wrongness. Sure, there are people who straddle the fence, in the realm of lesser wrongness, who may not appreciate they're doing some heinous shit. Some people are just plain fucking dumb, and go for the ride. Like some cops who think they're doing the right thing. Not the moral crusaders, and not the profoundly warped who trip on power. The middle-of-the-road reetarts, who just believe everything their daddy believed and don't fuckin' know why.
But the truly fucking sick, thats a whole 'nother story. We know we're not supposed to peel the skin off each other. Everybody knows that. But sometimes, war gives you a free ticket to dabble in the atrocities where we're not supposed to go. Literally, like an earthly being, being delivered safely into hell, and chaperoned, to fuck around in all the delicious delights of perverse behavior. And when they're done, no repercussions, just take your hat and go home. The true sadists are very aware of the opportunity, and know very few humans have ever had the "privilege" of being allowed to do these things.
And when you build a whole civilization on that, even for a few short years, sickness becomes very banal, ordinary. Those murderous cut-throats get to walk among us, and brag of their deeds. It tempts the urges of the unacquainted, and the whole civilizations primal temperature rises a notch or two. They say Berlin, during the war, was absolute debauchery. Prims became whorish, and gentlemen loutish and lewd. Fights were more deadly, and willing to go further than two men normally would.
I knew a guy, just a few years ago, who was a pretty decent guy, respectful of God and Country. Worked hard, and treated people right. He'd make a good neighbor, if you could overlook the bozo shit, and just wave across the yard.
His son went to Afghan on some kind of Special Ops detail, and had a bunch of clearances his father wasn't supposed to discuss. Good to his word, the dad didn't pass along much, other than the part I just mentioned, Special Ops.
One day he told me, when the kid got there fresh, they hazed him by putting an Afghani's hands on his keyboard, severed at the wrists. As a joke.
He told me this smiling, because I was interested in the news of the MidEast situation, but didn't really broadcast my deeper feelings, he assumed I was all HooRah. The part that disturbed me was not actually the hands. People at war do fucked up shit, and I would assume they were taken from a corpse. The part that disturbed me was the pride.
If I was in that fathers situation, switch places magically, I would need to go talk to a psychiatrist if I felt anything like pride, and I've never spoken to a psychiatrist (voluntarily) in all my life.
