The greatest virtue of Mankind-- Hatred

Amazed at my hypothesis! You have got every right to be. Any new idea as this, is always scrutinized with contempt and disdain. But if one analyzes this nonchalantly then you can definitely find some truth in it.
Think of the Indian National Movement, would it have been possible for the leaders of the National Movement to achieve their prized goal i.e. freedom, if masses of India weren't a part of the movement. And it is the unity among the Indians that ushered them a free India. And you must be thinking from where does this all is related to hatred. Yes, there is a definite co-relation. Was it possible for the Indians to unite if there wasn't a common consolidating force. And the common cause was hatred, hatred for the tyrant Britishers.
One can have more such examples, where hatred has turned out to be an unifying force.
Because of this virtue, many enslaved people have tasted the sugariness of freedom. But this virtue can turn into vice if it leads to the utter destruction of the parties involved. So one needs to be careful of it.
It has a rival too, love. My opponents would definitely term it as the greatest virtue. But may forget that it too comes with many freakish attributes. One cannot love a devil, if so , then he is going to slain you, ofcourse, for his love towards you!
Though it is still contentious but no one would disagree with the fact that hatred has its own virtues, if one really ponders about the subject. If one thinks a lot , then he/she would be content with the title.
