they aren't animals devoid of higher cognitive skills like bears, they're more intelligent than most mer, men and beast races.
and as such they are individuals, each with it's own beliefs and prejudices.

Dragon 2: Fiddlysticks! If we must fight, then let us do it with the most honor that is possible!
