Revisiting Discworld | The Watch, Book 1 | Guards! Guards!

Down there… are people who will follow any dragon, worship any god, ignore any inequity. All out of a kind of humdrum, everyday badness. Not the really high, creative loathsomeness of the great sinners, but a sort of mass-produced darkness of the soul. Sin, you might say, without a trace of originality. They accept evil not because they say yes, but because they don’t say no.

— Lord Vetinari, Guards! Guards! by Sir Terry Pratchett
