Trust the Ferret, the Ferret is Wise

I didn't mention "the devil made me do it" in any way shape or form, really. Well, the "rules" and "mortal or divine" bit, perhaps, but. There's more petty evils too, that are justified by being laws, things people do "because that's how things are," and so they don't even think about it. That's what it's aimed at, more the everyday little evil things, where people can shrug and go "Well, just doing what everyone else was/following orders/enforcing the law/etc. The point of the quote is that the thief, by being outside that structure, has to choose what to do, about everything, even the little things, and can't say "oh, that's how things are." Not about rule-BREAKERS, about people who follow the rules, even if the rules are bad. And the rest of the quote mentions how they knew that, as children, but got bogged down by things.
