Monsters and monster stories suit the culture that creates them. You can see this pretty easily by looking at the ancient monsters that ancient cultures created.

In western Europe, "eat me" monsters dominated, and the vast majority of both monsters and monster tales involved being killed and eaten. Vampires do not spread their state by a bite, they simply squat on your chest, eating your breath, until you die. Werewolves, similarly, just kill and eat you. Only later were new attributes introduced that made these monsters into their now-familiar forms.
