I think you're reading far too much into things.
Yes, it's logical that a scene would end at the point at which somebody points out that someone has died or was murdered - that's just the way drama is presented.
The 666? You saw one example and you think it's something. You're looking for the example and you found one. Not representative.
Finally, your whole premise is wrong. The "culture of death" is not about a concerted, directed effort. It's about decline.
