Well have you ever seen a werewolf then? 'Cause I haven't. And until I see one I will not believe in one. And before you go saying "Oh but if you saw one you would be dead!". How would people ever know what they looked like if everyone that ever saw one died?
And seriously, if I was a hypothetical werewolf why would I call attention to myself with outright stating disbelief? Wouldn't it be so much smarter to simply stay quiet and not draw attention to myself? So either I am a very, very abysmally stupid example of a werewolf for needlessly calling attention to myself, or I simply don't believe in such silly things and choose to say so.
Besides, all the evidence here is simply a badly mutilated body of our poor neighbor. It doesn't take a werewolf to do something like that. A regular wolf could do that, or even a particularly sick and twisted human. There is nothing to suggest that some creature out of a scary story did this. And frankly I think doing so probably insults Kaz's memory the more. We are chasing fairy tales instead of his killer, whether it is a wolf or a murderer.
*takes a breath to calm down and disengage preachy mode* Ok then, now that I got that out of my system. If you will excuse me, I have grapes to press and wine to bottle.
