“How easy is murder when one calls it by a different name? How much easier is it for the conscience to condone “reaping” than “killing”—and when one knows that death isn’t the end, does it stop the killing hand for fear of retribution, or does it simply make it easier to kill, because, if life continues, how can murder be murder at all?”

“Killing one person makes you a murderer. Killing a million people makes you a king. Killing them all makes you God.”

“Strange as it may seem—or perhaps it does not seem so strange—they all had the same thought: it was so much easier to kill humans on the battlefield than animals in cages, even if, on the battlefield, one might end up being killed oneself.”

“If I'm not a murderer," asked Corny, "how come I keep killing people?”

“Put it in terms of the not-too-serious, if you like. Who got into that locked room? And how was it done? And why should the cup have been moved again? We're up against the essential detective problems of who, how, and why. Simply because there was no murder or near-murder, does that make the mystery one bit less baffling?”

“Thieves are not so bad, and killing wears all possible costumes. There is no death, no murder that is better than any other. If you can kill me, the manner hardly bears consideration. You want to kill your own father, and you think it will make your sleep easier for the next seventy years if you can say you did it honorably. But your honor is blackened by patricide, and no amount of high-sounding formalities will make it white again.”
