"Other aspects of your character... are disctint liabilities. Inconvenient elements, such as a sense of morality, scruples, decency. So, I'm going to erase them. Replace them with an attitude more in keeping with your new life as a Reaver. Instant psychic re-programming. Like being reborn. No muss... No fuss, Presto Changeo... A whole new you! Isn't that nice?" -- Pretty Boy.
