Other mistake: At the end after the barn fire, Marcia is at a tavern, ordering a rare steak. While it is believable that she escaped the barn fire, it is unbelievable that she is in the tavern wearing the same dress and necklace she wore prior to her transformation in the barn. All of her attire would have been rended in the transformation and lost in the fire. Unless her wardrobe consists of duplicates of the same clothing.

Trivia: The man who is sitting on the couch with his wife watching the werewolf transformation on the news broadcast is a cameo from Mick Garris, director of such films as "Critters 2" and "Psycho IV: The Beginning." He also directed "Making a Monster Movie: Inside 'The Howling'".
Answer: He hated the way they were living. Acting human, hiding who they truly were, integrating into "normal" society. He wanted to be wild and free. When they were feared and worshiped.
