enoughisenough: How does that make you feel to know that you can do whatever you like and never have to be accountable?
I don't think that this is ever the case, regardless of the existence of a god.
1. We are social beings and we build relationships with others on a great many levels. There are a lot of things that I could do that would not be illegal or even wrong, yet I would be accountable for them because they might affect my relationships.
2. We live in societies where there are laws, regulations, and codes and we can be held accountable for the things we do by those societies. Even at a lower level, we deal with rules and regulations in workplaces, neighborhoods, public spaces, etc. We can be held accountable for our behavior in all of those situations.
I do not think that concepts of right and wrong are a problem for science. If we can reason out right and wrong, we can develop morals and ethics. No gods required.
