Why do people think of 狼男 as monsters

because, one of the first documentations of a werewolf was a killer. And that out 狼男 in a dark light.

Wtf?!? あなた serious? Wanna have a werewolf for a pet, または a best buddy? Cause they're monsters, that's why! あなた wanna pet, get yourself a dog, あなた wanna best buddy, get yourself some gay guy. Werewolves, vampires, ghouls, zombies, they're all monsters... Monsters like *ME*!!! Yeah, I'm a monster 2, a monster in human shape! We're all monsters when あなた think of it and we're all beasts deep inside. There's a wild beast sleeping in each and every single one of us, hidden deep in our subconscious, which sometimes wakes up, everytime when we get angry, just like all those teen オオカミ of Beacon Hills, even if we stay in human shape. Yeah, you're a monster 2, just like me! NS Wanna mess with a monster inside of me?!? Take a look in the mirror first! Look for a monster lurking deep inside of *YOU*. We're all fuckin' monsters, we're all wild animals! Monkeys with car keys! Got it? 666 is the number of the Beast, and that beast lies deep inside all of us, sleeping and waiting to wake up. Don't wake up the beast inside of you, if あなた wanna have a long life! People are オオカミ to each other anyway, even in human shape. No need to shift into a werewolf to become a beast. Ain't that what あなた had in mind? We're *ALL* fuckin' were\wolves, あなた and me both, just like this movie monster in this picture, only with a lot less body hair than this guy.
