I don't think I, as an aspiring writer of the horror genre, can come up with anything this macabre, this vile, this despicable. I'm the kind of guy who walks around my college campus, discussing grisly crime scene details into an RCA handheld voice recorder. I'm the kind of guy who can get into the heads of my characters. Even the serial killers. It's ugly, but I guess it's necessary if you want to achieve verisimilitude. The point I'm trying to make is that there's a good line between reality and fiction. For me, the suffering that the victims of my killers endure is unbearable, and keeps me up nights. For these psychopaths, writing fictional acts of sadism on innocents may be a pragmatic means of unleashing otherwise socially unacceptable behavior, or worse, warm-up sessions for real world carnage. The scary thing is the ambiguity. For all we know, this could be the work of a really good troll. Still, great find, OP. Keep us posted.
