I don't see what kind of positive statement this game could make, especially since you play as the killers.
I mean, there are other ways to provoke discussion about the killings. This just seems like another violent videogame to me and an old one at that. I can't comment on any gameplay merits this may have, if any, because I've never played it, but this doesn't seem like the kind of game I'd ever want to play.
The forum discussion is thought provoking, as well as the author's notes, however.
