"Why blame the Pastor, just because some lunatics decide it is ok for them to murder eight people, just because they happen to take offence at his actions? "
The Pastor new the likely result of his actions, and he knew that it was others he was endangering, but went ahead anyway. That doesn't, of course, justify the actions of the mob, but he has equal culpability in the deaths of innocents.
That's religion for you. The mob are telling themselves that God is on their side, and the pastor is telling himself that God is on his side, and meantime innocents are suffering for the stupidity of religious nuts, both Christian and Muslim.
