So in using your view of 'morality', the act of raping and murdering a five year old girl is not evil or sinful, its just not a good idea because someone may find out and hurt you in return.
Therefore in your version of 'morality', if you could be sure that there is no retaliation from another person for your crime, you can go ahead with it if you prefer, afterall, its not really wrong, its just that you might make somebody mad enough to get ya back.
This is the standard, empty, atheist view of morality, and its sick.
"One doesn't destroy what is precious unless one is ignorant or insane.
"As Schuon writes, "there is no comparison between the intellectual and moral worth of the greatest contemplatives and the absurdity that their illusion would imply were it nothing but that." Meister Eckhart or Bill Maher. Shankara or Sean Penn. Tough choice.
"Schuon goes on to say that this kind of hermetically sealed ignorance would lead us to believe that "no proof of anything is possible since every argument can be invalidated verbally by some sort of sophistry." In short, it is a reduction of integral truth to what the most common and vulgar minds are capable of understanding.

Is in your view of 'morality' dashing babies against rocks and raping their mothers not sinful because it is okay in the Old Testament? Is stoning your disobedient children to death morally right? The Bible says it is.
This is the standard, empty, atheist view of morality, and its sick.
