the werewolf image
Not all werewolves are the same, each is part human and each have their own feelings, emotions, and thoughts that they react to. I believe that the issue involving the bad image of werewolves is taken by the humans who have the rare bad occurrence with a wolf. Bad news goes around faster than good news. This rule follows the weighted one around making each wolf accountable for the few that make the bad decisions to cause trouble.
Even though it seems that humans have made a point of emphasizing the evil character of the typical prototype werewolf it does not mean that they are correct in their assumption that werewolves are evil. Many humans only know of the weighted one from movies, often knowing nothing more than the Hollywood prototype. They might be surprised to know that werewolves are closer to them than they think, often a co-worker, family member, or neighbor, probably some of the nicest people they know.
The werewolf has to listen do the scrutiny of the humans and mostly is never is granted an opportunity to defend himself. Humans are allowed to speak up, they are allowed to defend their image and control it however they see fit. I find the werewolf image to be doing quite well seeing as how werewolves cannot openly defend their it.
