Amazing. Extremely well-done. Well, "where do you stand?" Hmmm... Depends on the situation. Was the Crusader like those from the real world's history? And why are these other guys attacking the mother and child?
I sort of got this idea from real historical settings, The crusaders butchered a lot of muslim populations as they sacked cities along the way. I can't imaging the moral ordeal the naive young knights and soldiers go though to justified the truth in front of their eyes, what if choosing to protect the innocent means becoming the enemy of your comrades and your very own faith?
That would be tough. Plus, if you had real faith (at least according to my school's religion teacher (i'm not religious, but I go to a Catholic school)), even if you were excommunicated by the Pope, that wouldn't mean anything - the Pope is simply a conduit through which "God" can display his apparent orders/desires, and a corruptible one at that.
