This Way to the Gas, Ladies and Gentlemen” by Tadeusz Borowski

From the text:

“It is that very hope that makes people go without a murmur to the gas chambers, keeps them from risking revolt, paralyses them into numb inactivity… hope that breaks family ties, makes mothers renounce their children, or wives sell their bodies for bread, or husbands to kill." (pg. 122)
