“He who fights with monsters should be careful lest he thereby become a monster.”Friedrich Nietzsche · Amurgul idolilor · 1888 · Maxime și săgeți, 46
When you wield the enemy's weapons, his victory becomes your defeat of yourself.
The warning targets contamination through prolonged exposure: to defeat a monster you must stare into it for a long time, and that gaze leaves marks. Fighters of evil often end up borrowing its methods, justified as necessary, and becoming what they hated. A classic case: an anti-corruption crusader who, over the years, resorts to exactly the blackmail and lies he once denounced. Nietzsche adds the second half: gaze into the abyss long enough, and the abyss gazes back into you.
The card says: check your means. Let's go further: the check is not a one-off gesture, it's a routine. Nietzsche suggests the change is slow and silent, so it never announces itself. That's why it needs fixed moments in your personal calendar. A simple trick: once a month, write down one thing you did to win, not just what you defended. If you lied or pressured someone, ask: would I have condemned this a year ago? An activist rereading old messages can see precisely how much the tone has shifted. The abyss does not gaze at you all at once; it gazes a little, every day. And if the change is gradual, a natural question follows: what did you actually look like before the fight?
Why it matters A warning for anyone fighting an enemy: check regularly whether your methods have become the enemy's own.
