“What’s the difference? Fill a hundred pits with dead Northmen, congratulations, have a parade! Kill one man in the same uniform as you? A crime. A murder. Worse than despicable. Are we not all men? All blood and bone and dreams?”

“Kill one man, and you are a murderer. Kill millions of men, and you are a conqueror. Kill them all, and you are a god. Thoughts of a Biologist”

“Man has no right to kill his brother. It is no excuse that he does so in uniform: he only adds the infamy of servitude to the crime of murder.”

“The sins of good men are greater than the sins of bad men. One lie from a truthful man is more hurtful than all the lies of a liar. The sins of a man after God's own heart have done more harm than all the crimes of all the Pagan emperors.”

“What difference does it make after all?--anonymity in the world of men is better than fame in heaven, for what’s heaven? what’s earth? All in the mind.”

“No matter how limited their powers of reason might have been. still they must have understood that living like that was just murder, a capital crime - except it was slow, day-by-day murder. The government (or humanity) could not permit capital punishment for one man, but they permitted the murder of millions a little at a time. To kill one man - that is, to subtract 50 years from the sum of all human lives - that was a crime; but to subtract from the sum of all human lives 50,000,000 years - that was not a crime! No, really, isn't it funny? This problem in moral math could be solved in half a minute by any ten-year-old Number today, but they couldn't solve it. All their Kant's together couldn't solve it (because it never occurred to one of their Kant's to construct a system of scientific ethics - that is, one based on subtraction, addition, division, and multiplication).”
