While looking up a different Friedrich Nietzsche quote this afternoon I chanced upon this one and immediately was struck by both its truth and it's eloquence and I'm a guy who doesn't much care for the works of Mr. Nietzsche for what it's worth:
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."
