I wouldn't let anyone harm a child. I'd rescue them, no matter the risks. And if we're talking about crusades against Urgash, I wouldn't participate in them. It's not my thing. Crusades, attempts to impose one's faith – these are all ideas of the Light, and I am as dark as the moonless night. The Dark ones live as they please and don't interfere with others doing the same.

But are they really the "Light," if they do such things?

I'd like to point out that Richard was nicknamed "Lionheart" because he ordered the execution of two thousand prisoners when the Saracens failed to meet his demands. The hero of legends is a ruthless barbarian, whose actions even horrified the Saracens (against whose "infidelity" all those famous pilgrimages were directed).
I agree with Alexey that if we lived during the time of the Crusades, we would kill without hesitation in the name of faith, the holy throne, Christ, and all the saints. The question arises, where is the Gospel in all this? And what kind of faith is this?

Ganymed, even considering the fact that I would live during the time of the Crusades, I wouldn't kill children, but I would stand in the ranks of the army of Alexander Nevsky, which was three times smaller than the crusader army, and defend my native land. Alex, yes, I am writing and saying all this while sitting at a computer, but let it be known that I have more than once gotten into trouble with high school students when I stood up for third-graders. And not just me. And you know, it's not that difficult! Just don't, sitting at a computer, not seeing the world and the people who live in it, say that all people are born as cutthroats. The Crusaders killed not because they were evil creatures, driven mad by a long journey through the desert, but because they believed they were doing the right thing, spreading the word of God in this way. Surely you know that at that time some people didn't even consider other people to be people. For a Catholic, a heretic and the devil were practically synonyms. So don't jump to conclusions.
