I think one of the most important purposes of morality is to keep people smart and interesting. I grew up in a pretty sheltered Christian environment, and the difference between how I thought and they way the jaded teenagers at public school thought was very distinct. The behaviors that are traditionally considered sinful end up making the sinner a boring and small minded person in the long run. This is essentially because sin destroys a person's imagination. The object of sin is usually a very strong, visceral pleasure, and if there is anything that can control the focus of a person's mind it is strong, visceral pleasure. And, when I am thinking about pleasure, I'm not really thinking about anything. It is just a feeling, and feelings don't have any kind of logical content that can lead my mind to other thoughts. Finally, engaging in visceral pleasure makes everything else seem boring by comparison, while also requiring a greater amount of the pleasure's source to get a thrill. The combined result is me having a one track mind, constantly thinking about nothing.
