By Friedrich Nietzsche
He who fights with monsters should be careful lest he thereby become a monster. And if thou gaze long into an abyss, the abyss will also gaze into thee.

About this quote
From aphorism 146 of Nietzsche's Beyond Good and Evil (1886), in Helen Zimmern's English translation (New York: Macmillan, 1907). Nietzsche wrote in German, so this is the translator's wording.
