There have always been funeral/burial rites in all traditions, long before the Victorians.
In Victorian times children grew up with deaths of people of all ages, not morbid, it was normal & not a taboo subject; there were things people did when someone died, depending on their own beliefs & traditions. It has become less and less so & young people particularly find death hard to deal with especially disposing of the body. I've known people to be quite scared of that & have the attitude that the sooner it's over & the less anyone has to see or think about the details, the better.
No-one can help how they feel but having and giving support and observing some sort of tradition can be useful.
