Now when it comes to another adult person, they may not have come to this way of thinking and so they may feel great anxiety regarding death. However, perhaps children have a different perpective "on life and death" - often times they have a kind of fearlessness since they aren't fully enculturated yet (I base this on a story I heard of how a young girl with cancer was not afraid at all).
Instead of pity, it seems that the natural response that would arise, toward those we love, would be compassion and so we might want to comfort them if they feel anxiety toward the thought of dying. Also, parents who are about to lose a child (or have lost a child) might feel a lot of anguish, and there isn't much that we can do except to say "I am here for you if you need anything".
In my mind "pity" is somewhat artificial and based on abstracted ideas/ideals. Where as compassion that is directed toward action would be PD5 -- acting according to necessity for the best life.
