Seriously, if there were no morality, I would still have tastes, and they would still involve being fairly nice to people, but I'd generally put myself first and not worry about it. I'd sometimes be a freeloader or slacker, but not to such extremes that I could see how my actions hurt other people. I'd generally be a productive, sympathetic person, but not terribly heroic or altruistic. I would ... not be much different from the way I am now. But without the guilt. Without the sense that that can't possibly be enough.
