@JPB,
I had a conversation about this with my mother two years ago. A good friend of mine---"Diva" to many A2K people---had suddenly died of a blood clot. My mother, a theologically liberal but devout Protestant, tried to help me by suggesting that Diva was now in a better place, and that I might feel less miserable if I believed that.
I demurred: Even if I
wanted to make myself feel better by believing something that I didn't think was true, it wouldn't have worked. What difference did it make
to me if Diva was in heaven, or in hell, or nonexistent? Either way, she was
gone, I was missing her, and
that was the reason I felt miserable.
Eventually, I got over all that with the help of long walks on the beach, lots of playing Bach preludes on the piano, and, I'm embarrassed to say, overeating. Contemplations of any afterlife---pro or con---played no role whatsoever.
