Each one should observe three principles in life - Love for God, Fear of Sin and Morality in Society. You should realize that the soul, the Divine and the Society are all aspects of the Divine. Lack of fear of sin in human beings is the root cause of the absence of morality in society.
One bereft of morality is not a human being at all. For everything, morality is important. God loves all. If one has love for God, there will certainly be unity in society.
People indulge in sinful deeds despite knowing that God can give them punishment. They have no fear of sin. If one lacks fear of sin, there can be no morality in the society. If everybody has fear of sin, then there will be morality in the society.
