I think the topic starts with How can moral values be developed..from where do we learn what is good or bad for the human being.......I think all the religious books presents stories in order to frame our minds about the goods and the bads.Good is something which does not harm the natural beings and the bad is something which destroys it .All the cultures, society, religion, nations, family together form a notion which become a moral value.I come from a family where killing a animal is considered immoral, we are vegetarians, no one smoke, no one drinks alcohol.Now these all things happen in the world and are not considered immoral by some.Religions we follow are based on our personal suitability.and how many of us do follow all that is written in the religious books..I guess not many.We are selective in following the rules..and make our own personal values and moral values as we grow as per our own personal experience
