Perhaps an argument for increased "death awareness" would be that the realization that we and everyone else should die is structuring in some sense. It provides frameworks for life and everyone is included therein; We are all faced with the same conditions. Even if death did not exist, it might even be a good idea to invent it. One can recall the famous piece of Tertullian, who writes about a Roman emperor:

Even when, amid the honours of a triumph, he sits on that lofty chariot, he is reminded that he is only human. A voice at his back keeps whispering in his ear, "Look behind thee; remember thou art but a man" (Tertullian.org, 2015, April 5).
