I agree with you, but this depends on how the culture view the soul. If it is clearly defined to be something distinct from the body, the dynamic could be different with regard to the recycling of the corpse: after all, some real world culture (unless it's an urban legend) dispose of the corpse by exposure. Would we grieve this much if we knew for certain that the relative is elsewhere and is happy and OK to be in the afterlife (because he declines to be resurrected, for example)?
I could see better acceptance for skeletons than for well-preserved corpses, for example.
