Mr. Anand, It looks you have read Quran (if not, go and read first!) but not with open-heart, but with revengeful, prejudice and biased heart. Even if u take medicine under these situations, than its of no-use, if I am wrong go and ask doctors. Remember, no religion advocates evils, even if my own brother muders an innocent non-muslim, then Quran says its like killing all humanity. And my brother should be hanged, irrespective of his religion. It is not like he is of my family or caste, so he should be punished less. No, hanged him, in the sight of one God, all are equal, ranks are according to his fear we possess in us,and nothing else.
But only thing is that guilty should be properly established in the court.
