Obviously the sn64gces didn't read the comment....
I feel I should clarify something for anyone who might try to flag this as a warning sign (or something to that extent); this submission, and many like it, are not uncommon, on this site or others, and most of the time are not a foreshadowing of something the artist necessarilly wants/intends to do, but is mere creative expression (even if gruesome.)
It would be almost impossible to predict what happenned after "Jeff" submitted this. I'm almost certain that some people may blame this site or the people who frequent it for "not taking notice and trying to stop this or warn someone." Feelings of violence are commonplace, as are feelings of happiness, sorrow, laughter, etc. If I had not seen this after reading about it's story, I wouldn't have thought anything different from any other movie like it.
