A community where everyone is a ruthless murderer, with handy access to death-dealing devices, is a very polite community.
Robert A. HeinleinConsider the black widow spider. It's a timid little beastie, useful and, for my taste, the prettiest of the arachnids, with its shiny, patent-leather finish and its red hourglass trademark. But the poor thing has the fatal misfortune of possessing enormously too much power for its size. So everybody kills it on sight.
