There was a girl, and her uncle sold her
There are accounts that, if we open our hearts to them, will cut us too deeply. Look-here is a good man, good by his own lights and the lights of his friends: he is faithful and true to his wife, he adores and lavishes attention on his little children, he cares about his country, he does his job punctiliously, as best he can. So, efficiently and good-naturedly, he exterminates Jews: he appreciates the music that plays in the background to pacify them; he advises the Jews not to forget their identification numbers as they go into the showers-many people, he tells them, forget their numbers, and take the wrong clothes when they come out of the showers. Our man supervises the detail taking the bodies to the ovens; and if there is anything he feels bad about, it is that he still allows the gassing of vermin to affect him. Were he a truly good man, he knows, he would feel nothing but joy as the earth is cleansed of its pests.
