If you crush a cockroach, you’re a hero. If you crush a beautiful butterfly, you’re a villain. Morals have aesthetic criteria.
— Friedrich Nietzsche
For the record, I’m not sure I completely agree. Generally, right is right and wrong is wrong. But I do think when we react instinctively to things, even more things, we impart our own “aesthetic criteria”. I don’t think it’s necessary to judge that… just to be aware.
