You have asked a question in the article "Do we need to see even the most despicable things that happen around us through a prism of caste, creed, religion, political parties, competition, business, sex, region, and so on?"
Well just read the discussion and you will find the answer. Its no more about right or wrong, its just revenge and hatred which has spread into the Indian community.
All I can say are two wrongs dont make a right, if youe loved ones get hurt do you feel justice is done by killing somebody else who is innocent or by finding the person who caused harm and punishing them.
Gandhi had said "an eye for an eye makes the whole world blind" how true was he. It seems the whole world has gone blind
