Man and his deed are two distinct things. Whereas a good deed should call forth approbation and a wicked deed dis-approbation, the doer of the deed, whether good or wicked always deserves respect or pity as the case may be. Hate the sin and not the sinner is a precept which though easy enough to understand is rarely practised, and that is why the poison of hatred spreads in the world.
For a bowl of water give a goodly meal; For a kindly greeting bow thou down with zeal; For a simple penny pay thou back with gold; If thy life be rescued, life do not withhold. Thus the words and actions of the wise regard; Every little service tenfold they reward. But the truly noble know all men as one, And return with gladness good for evil done.
Non-violence is the greatest force at the disposal of mankind. It is mightier than the mightiest weapon of destruction devised by the ingenuity of man.
