religion gives u a guideline of morality and tells you the good thing that you should do. But, does that mean people would have been immoral and evil without any religious guidance ? Wrong.
the feeling of just actions, proper things to say or do exists in a man's mind as well as his recognition to the evil deeds. In his mind, he is semiconciously aware that as much right he have to live, to say the truth ( truth in a sense making the statement about something as it is ) comes along human nature. Being honest and dishonest both exist in human nature.
Most of the country laws , if you can review it, is built up by the laws of natural morality, which states that all people have the equal right for something. It didn't take a religion to write these laws.
