Religions claim to be the source of our values and morals.
Yet, being reminded of what is good, hopefully will nudge us in the right direction. Either directly or indirectly, religion is a strong influence upon the civil rules and regulations that exist in any given society. If that person fails to think things through more completely, it is easy to renounce the moral values right along with the religion that pronounces those values. And most of the time, even when these individuals appear to be acting unselfishly, there is generally a hidden selfish motive lurking inside them which drives them to exhibit unselfish behavior. In other words, its just more selfishness.
