"Do you know, I've decided I like guns. Of course it would be preferable to wave a magic wand and have all sentient life live in peace and harmony in paradise forever. But if Reality puts you in a situation where you have to kill, at least we have tools to do it quickly: a well-aimed bang and there isn't a creature there to suffer for very long. That's actually a huge improvement over the state of nature, where animals kill with nothing but teeth and claws."
