For the comment, i have no idea. Reminds me of those people who, unsolicited, leave comments of a similar nature on youtube videos for reasons beyond imagination. I did some research on the picture used. The picture was an "art piece" by some guy on a forum site. As of 2010 (I can't be bothered to do more research), the man who made it is mired in controversy due to its realism and incredibly violent tone. The owner of the forum was going through a lawsuit because of said guy.
Hope that alleviates some of that desire for the lore.
