I agree. Without the murders, what I see is a guy who is simply not too graceful. There is another video of CW, made a few years ago, before his weight loss. He is in his kitchen, in a wide shirt, singing (to a dog? Not sure). All I can see is that he has imperfect pitch and moves out of sync with own singing, and the video is funny, but that is all. Yes, slightly nerdy, but this is not an explanation for his actions. Interestingly, it seems that his nerdiness generated some fun at home, as on Metallica video, SW's father, good-naturedly, posts something like, "sounds like Chris is having fun". Overall, a normal video, a normal family, normal responses. But it was a year ago, before SW was deep into marketing of her product, I understand.
