My guess is that the FC pax reacted like any other Westerner that does not see dead human bodies very often.
Even 50 years ago, children would see their grandparents, aunts/uncles and even siblings laid out in the front room for everyone to pay their last respects. By the time they reached adulthood it was not quite a common place but nothing unusual.
Nowadays, we only see dead bodies in extremis and VERY rarely are they brought into the library-quiet FC cabin. Also, the journo asking the question would have been looking for a sensationalist reply.
Sounds like the cabin folks and the dcotor did all they could and we should have sympathy for them. Not to mention for the widow.
Some A340s have a storage compartment that can be used for bodies, I recall seeing a photograph of it on Airliners when this subject was discussed here on a previous occcasion. I cannot find the image off hand. However, that would only be suitable when the person that died was travelling alone.
