"To tell the truth, one did become used to it... they were cargo. I think it started the day I first saw the Totenlager [extermination area] in Treblinka. I remember Wirth standing there, next to the pits full of black-blue corpses. It had nothing to do with humanity — it could not have. It was a mass — a mass of rotting flesh. Wirth said 'What shall we do with this garbage?' I think unconsciously that started me thinking of them as cargo."
