The idea of cultural relativism started from the society. From the society it turns out to be a symbol of that particular area and become mass/universal. According to Rachel (p.18) says " These customs cannot be said to be "correct" or incorrect, "for that implies that we have an independent standard of right and wrong by which they may judge".

There were more deaths among males as compared to the females. Furthermore,
