Conclusion

In principle, it would be entirely possible to replace religious-inspired morality with logically derived concepts of morality in human life. Generally little else would be required besides suspending religious teachings and substituting the rules of organized religion with very basic ideas such as "do no harm." In that regard, the commandment "do unto others" is a perfectly useful and easily understandable ethical principle that could be taught with much better results without the cloak of its religious context.

Instead of teaching that human beings are incapable of ascertaining what is right and what is wrong without divine help and that we are morally tarnished by our involuntary thoughts, we would learn that one ought not to treat other unfairly or cause them harm and that the worse our involuntary desires and thoughts, the more moral credit we deserve for resisting the impulse...

Ultimately, one of the saddest aspects of religious morality in human society is precisely how easily moral conduct could be taught but for the cultural brainwashing inherent in religious education.
