Read it and then come back.
There are no words in psychotherapy which manage to encompass or convey how vast and profound this effect is, though I do not think the psychotherapist has been licensed who does cringe in awe before it. We know; of course we know. We're not allowed to be blind enough not to see it. What is the Active Listening statement you make in reply to a man who tells you the only reason he's alive is that he out-drew an eight year old girl with a gun and a four month old baby?
The only language which comes close to containing this is that of religion: even we psychotherapists, as in a quote in the article, find ourselves reaching for the world soul. Not in a supernatural sense, but in an essential sense. It is the soul which is deformed by the act of killing, no matter how righteous and justified that killing may be.
As so many religions teach: If you murder, you will go to hell. But not in the afterlife. Right here, right now.
It will not matter that you were justified or that your cause was righteous or that you followed the rules, the law, or your orders. There are laws which are not laws of man, but laws of nature. They are subject to no mercy, they make no exemptions, as much as the madmen of the religious right claim otherwise. We have religiosos in our midst who, like those of old, exhort their followers that no harm can come to the faithful, only now it is wounds of the spirit, not arrows and bullets of the enemy, which shall never lodge in the faithful heart. They have stopped believing in the truer part of their religions.
To ask someone to kill for you -- for your nation or your cause -- is to ask them to sacrifice not merely life and limb, but possibly also their mortal soul; to accept their may be spiritually maimed or mutilated. However grievous it is to lose a leg, what is it to lose one's capacity to know peace within oneself? Has the prosthetic been made for the human heart so it can embrace again when it has lost that faculty? Is there a surgery for rebuilding a man's shattered self-regard, self-confidence, or self-love? Can we excise embedded nightmares, shattered bits of toxic reflexes, putrefying memories?
These are not without treatment, but, in our society, they are largely without acknowledgment. They are costs which the Right has swept under the rug; to say any ill will happen to the souls of our soldiers is tantamount, they shrilly claim, to calling those soldiers bad people. There must be no public discourse which suggests our sons and daughters don't come back to us in one piece; they claim it is an insult to the injured to acknowledge the injury.
Were our society more pious or humanistic we would have a language to speak this truth to power. But neither religious accounts of the soul nor science's inquiries into the mind are, in our age, of sufficient consequence to move the hearts of men. We are dumb before cynical materialist hawks' insistence that there is no such thing as sin, or soul, or mind.
So no account is taken of this other sacrifice -- which doubles the cost already reckoned in shattered bodies and blasted futures -- in tallying what this war is really costing the American people.
This is reason enough, besides all the other reasons, why our soldiers must never be committed to a fight except for the very best of reasons. They are not tin soldiers. They are not game pieces on a board. Those who survive will carry their battlefield deeds with them off the battlefield, and into every day of the rest of their lives. They are the flower of America and the magnitude of their magnanmity in accepting that risk should be honored by employing it only to such purposes worthy of so great a nobility.
