“I believe in our side and theirs, with the good and evil decided after the fact, by those who survive. Among men you seldom find the good with one standard and the shadow with another.”

“Hate not those who reject you, who insult you, who abuse and slander you. Hate not the atheists, the teachers of evil, the materialists--and I mean not only the good ones--for there are many good ones among them, especially in our day--hate not even the wicked ones.”

“Men who believe in good and evil, and who believe that good should win, should watch for those moments when it is possible to play God”

“Later, with time, I learned that although all men are capable of good and evil, the worst among them are those who, when they commit evil, do so by shielding themselves in the authority of others, in their subordination, or in the excuse of following orders. And even worse are those who believe they are justified by their God.”

“Nowadays, no one believes in evil. It is considered, at most, a mere negation of good. Evil, people say, is done by those who know no better - who are undeveloped - who are to be pitied rather than blamed. But, M. Poirot, evil is real! It is a fact! I believe in Evil as I believe in Good. It exists! It is powerful! It walks the earth!' He stopped. His breath was coming fast. He wiped his forehead with his handkerchief and looked suddenly apologetic. 'I'm sorry. I got carried away.”

“I thought we were the good guys,” he said, and it had that note of a child who finally realizes that sometimes good and evil aren’t so much opposites, as two sides of a coin. You toss it one way, and it looks good, another way, and it’s evil. Sometimes it just depends on which end of the gun you’re on.”
