not much to say about this but necessary to acknowledge perhaps

here is a link to the Gerstein Report, i think the only eyewitness account of the holocaust by an SS soldier
http://www.holocaustresearchproject.org/ar/gersteinreport.html

"Even in death one can still tell the families. They still hold hands, tensed in death, so that one can barely tear them apart in order to empty the chamber for the next batch. The corpses are thrown out, wet from sweat and urine, soiled by excrement, menstrual blood on their legs."

and, on the other side, a .pdf of Primo Levi's 'If This Is A Man'
