Okay, to all the haters for my post: First it was asked what my opinion was. My reason for that explanation is most every culture and religion has an adversity to adulterous behavior. This behavior may vary but in general is the same. Some were formulated off presumed enlightenment while others were from observable reactions. If course, another reason was to expand or continue the bloodline, increase followers of the religion, more bodies to work or fight for the ruler, or just to brag on virility. The most common are jealousy, a feeling of betrayal even if allowed, divorce, mistrust, fighting, and still in today's society murder of the lover, mate, and possibly self. Just look at the news today with lawsuits for infidelity, divorce, and murder. There were reasons these traditions started.
