Battle not with monsters, lest ye become a monster, and if you gaze into the abyss, the abyss gazes also into you.

Be careful when you fight the monsters, lest you become one.

God is dead.

He who fights with monsters might take care lest he thereby become a monster. And if you gaze for long into an abyss, the abyss gazes also into you.

I am a law only for my kind, I am no law for all.
