War is necessary sometimes, even in the Bible... The crusades were to reclaim the Holy Land, whether there was a mandate from God regarding this, I don't know... myscrnnm, don't twist this...
The Crusaders who went to the Holy Land were not good people. Not good people at all. I mean, compare them to the Muslims during the conquest, and the muslims had better trained armies, better literature, culture, etx. They made the Europeans look like barbaric. And the Europeans acted that way, too. Ever heard of what they did when they took Jerusalem? And what Saladin did when he took it back?
