Many God-fearing persons will indeed go around killing others in the name of religion, because they believe that their god will be pleased by that. Murder in god's name is not blasphemy, not worshipping that god is. And those committing that blasphemy are fair targets.
Many Indians also sing patriotic songs on indepedence day and republic day and many also have love and pride for the nation.
Many American people must have joined together and prayed to your god for a long time - did that prevent 9/11?
The fact is that there is no supernatural god to listen to prayers and intervene in this world based on that.
If everything happens as per god's will, and god has a plan, isn't it audacious to expect that his will and his plan should be changed because of the prayer of someone who himself says that he is full of sin? Think about it.
