Werewolves, no matter how civil, would always have that beastly side that was hidden beneath their subconsciousness, deep in their heart, engraved in their skull. This beastly side was necessary to survive, to thrive in the wilderness when killing was often the only other option after getting killed.
Werewolf packs of ancient times used to engage in ferocious battles over territories and food. It was not rare for one mighty werewolf pack to completely destroy another pack and take over its territory.
Along with the progress of civilization and the decreasing number of werewolves, packs were discouraged from engaging in wars. Even if such wars were to happen, the winning pack must minimize casualties. Unnecessary deaths must be avoided to preserve the precious werewolf bloodline.
