Morality is the herd-instinct in the individual.
Friedrich Nietzsche
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.
Never let your sense of morals prevent you from doing what's right.
Isaac Asimov
Without cruelty, there is no festival.
He who fights with monsters should be careful lest he thereby become a monster.
