As I write, highly civilized human beings are flying overhead, trying to kill me.
They do not feel any enmity against me as [an] individual, nor I against them. They are “only doing their duty”, as the saying goes. Most of them, I have no doubt, are kind-hearted law-abiding men who would never dream of committing murder in private life. On the other hand, if one of them succeeds in blowing me to pieces with a well-placed bomb, he will never sleep any worse for it. He is serving his country, which has the power to absolve him from evil.
