Throughout the human history, believers of all sorts have claimed divine support for bloodbaths that they themselves have committed.

After reading this article, I was reminded of the crusaders that conquered Jerusalem in 1099. After massacring at least 30 000 civilians, all Muslims and Jews(3000 of which were burned alive in a synagogue) of the town and those of it´s Christians that weren´t able or given chance to proclaim their religion, they went to the supposed grave of Jesus and prayed to thank God for the great victory he had given to them. The will of God had come true, they thought.
