In fact, even with good intentions and level heads, if we give in to our lesser instincts too often there’s a far more likely outcome than “we become black market weapons dealers.” It’s simply that we become selfish. We start to believe that our own “right” to do whatever we want, whenever we want to do it, is more important than anything else, and thus our sense of morality concerns only our own happiness or pain. We become… Ayn Rand.
