I see no bad coming from getting comfort in the religious thought of an after life I just don't feel it. Anything that can be done to ease the distress of the person dying I'm pretty much all for.
My thoughts on all of this are pretty concrete. I don't even go to my daughters grave cuz I just don't feel like I need to stand there next to where her body has decomposed. Morbid? Maybe. It causes me to struggle with what I want when I die. What I want for my family. Will my kids want a grave to visit? Will they be ok with visiting somewhere my ashes were released? Will they feel like I do now and not need a physical presence to have a moment feeling closer to me? This is the tough pat that I'm dealing with right now. And in all of it I never think "well just in case God exists I'd better do..."
