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.

Author: Friedrich Nietzsche

Insight: When you're fighting something you despise—whether it's corruption, injustice, or even just someone's cruelty—there's a seductive trap waiting. You can become so consumed by opposition that you start using the same tactics, the same ruthlessness, the same dehumanizing logic you were fighting against. The crusader becomes the tyrant. The moral warrior becomes the bully. It happens quietly, justified each step of the way. What makes this warning sharper is that it's not really about monsters at all. It's about attention itself. Where you focus your energy and rage has a way of reshaping you. If you spend years staring at corruption, studying it, building your identity around being against it, something shifts. You begin to see corruption everywhere. You begin to think like a person at war. Your normal human kindness gets filed away as naivety. You start seeing enemies instead of people who made mistakes. The real insight isn't that fighting for something good is wrong. It's that you have to regularly pull your gaze away. You need relationships and interests and joy outside the battle. Otherwise, even the righteous fight will hollow you out and leave someone very different standing where you used to be.
