Oh God I have to keep this post short, I study history, political science, and philosophy and I really don't want to go into a huge argument over this subject (as I do this about 15 hours every week). Basically many of the examples you've provided have changed through history over and over again, that's a product of societies. In taking part in the 'social contract' many of our natural instincts must be surrendered in order to function successfully with others. Hobbes pointed out that we surrender our natural rights once we enter a society, as the way we acted within nature was simply to protect ourselves. We give up absolute liberty for security, that's how societies go. Concepts like 'murder' and 'theft' are shunned because it acts against the social contract, it's deliberately damaging the system of order and forcing a 'return to nature'(Hobbes was clear that this is bad, the lives of those in nature are 'nasty, brutish, and short').
You're right about morality though, it's not a product of religion, morality is actually a product of society and the social, political, and economic factors that affect it. Religion is then shaped by this morality, hence why throughout history religious groups have picked-and-choose what passages they believe to be holy, as these passages are the ones that their societal values are reflected in.
