That's a gross oversimplification of history. Now, how did that BlackHawk Down quote go... ? Ah, yes : "Don't make the mistake of thinking that because I grew up without running water I am simple."

Same goes for medieval minds : just because they lived in a world where the tolerance for violence was higher than ours, don't make the mistake to believe they were all cruel and genocidal folks, or dimwits blinded by religion either.

Admitedly, chivalry as we know it is pretty much an invention of the Renaissance, but you don't have to adhere to some kind of Bushido to figure out the Golden Rule, do you ? After all, it's a matter or basic survival :/
