What's the point of being a werewolf anyway?

He runs around and kills, kills, kills, slashes, maims, rips chunks out of bodies, kills, runs around, runs........ to awake in a hollow tree the next morning.

So that is the life of a werewolf? A real wolf would only kill to defend himself or to eat, first and foremost, I'd say. But being a werewolf is just going on a killing and slashing rampage, like being on a VERY bad trip? Totally psychopathic and nonsensical except being "bad"?

The goal for a "good" werewolf is just to kill as many people as he can? What happens after he has killed the last person on Earth? He's sitting by a lake, tossing stones in the water and getting terribly bored, I presume...
