the beauty of being immoral
By doing a virtuous action once and only once you are not a moral agent but merely virtuous by accident. in order for your virtue to shine through you must first suffer for it. Take the example of the brave man who acts upon the virtue of courage in order to jump in front of a bike in order to save a toddler from harm, the man is accidently brave as it would be an act of spontinuity and not habit; he would also end up with some disfigurement to his face as the reward for his courage.
In order to become moral there must be some consistantcy in your virtuous actions in order to habituate your virtue, this requires suffering and would put off most people who fall under the category of psychological hedonists. Let us return now to our brave man illustration; the brave man (to be fully brave and hold the virtue of courage in perfect balance) he would have learned to jump in front of every oncoming bike in order to save anyone in its path, not just the one off event of the toddler. by repeating this act several times he has come to become brave however during this period of habituation he would have suffered a number of disfigurements to his once unblemished face.
I doubt anyone out there would disagree with me if I was to say that the disfigured face holds beauty within itself (beauty within the person is another matter) yet the face would still hold the virtue of courage as it shares the same virtous faculties as the agent it belongs to. Instead beuaty remains in the unblemished face of the unvirtuous coward. Therefore beauty lies in being immoral.
Furthermore being moral requires us to endure pain and suffering which would require us to go against our nature as psychological hedonists, hence morallity requires us to act against human nature, show endurance, be motivated, suffer for out viirtue and abstain from earthly pleasures.
To conclude it is much harder to be moral than in it be inactive and remain beautiful but immoral.
