I agree with you, that was the aim of such camps (I'm also thinking of the Nazis here), and for most of the people, that probably was the result. It broke so many people who physically survived, too. And I think it's important to not focus so much on the "silver linings" of this "cloud", to avoid the sheer horror of it. But all that being said, "L'Espèce humaine" by Robert Antelme is a book worth reading. I only have the German translation:
> Die SS, die uns miteinander verwechselt, vermag uns nicht so weit zu bringen, daß wir uns verwechseln. Sie können uns nicht daran hindern, unsere Wahl zu treffen. Im Gegenteil, hier ist die Notwendigkeit, seine Wahl zu treffen, maßlos gesteigert und konstant. Je mehr wir uns verändern, je mehr wir uns von zu Hause entfernen, je mehr die SS glaubt, uns zu einer unterschiedslosen und verantwortungslosen Masse zu machen, was wir dem Anschein nach auch unbestreitbar sind, um so schärfer werden diese Unterschiede.
> The SS, which mistakes us for one another, cannot bring us so far as to make us mistake ourselves. They cannot hinder us to make our choice. To the contrary, here the necessity to make one's choice is limitlessly increased and constant. The more we change, the further away we get from home, the more the SS believes to have made us into an undifferentiated and irresponsible mass, which we undeniably are on the surface, the sharper these differences become.
I can't speak for any of this, either way. As I said, I'm mainly with you, and I certainly don't want to glamorize concentration camps. But for what it's worth, I recommend this book.
