" Now, even if he and Dr B made their decision, D didn't know if he had the rigour to feed the cyanide to the ill, or to watch someone else do it and maintain a professional disposition. It was absurdley like the argument in one's youth, about whether you should approach a girl you were infatuated with. And when you'd decide, it still counted for nothing. The act still had to be faced. "

― Thomas Keneally , Schindler's List
