He who fights against monsters should see to it that he does not become a monster in the process. And when you stare persistently into an abyss, the abyss also stares into you.
Behind the line
What it means
Our interpretation.
The speaker warns that opposing monsters can slowly turn a person into one, and that gazing long into darkness lets the darkness reach back. The two sentences describe moral contamination: sustained fixation on evil, or fighting it without care, can reshape the fighter. Vigilance includes watching oneself.
