Yeah but if you believe in the afterlife then you also have to take the chance that you’ll be spending all eternity hearing that damn song from the Lion King.
I bet it would wear after year 57 or so…
See a better use would be to process and freeze the bodies: “Corpsicles, New Blood type A flavour, Yumm!”
Or from South Park…
“It’s the poo of the antelope, the poo of the giraffe…”
That’s exactly what my instructions say 
That could be arranged today, if you like the idea so much…
I’m not so sure that work out so well, what with all the kicking and screaming scaring off the vultures and hyenas.
I quite like the idea of being buried in a cardboard coffin, with a tree planted over me. Well, you know, after I’m dead and all.
Polar bears don’t need to develop a taste for human flesh; they will stalk and kill humans when they see a chance—they’ve been doing it for many years. I don’t know that its ever been proven that sharks develop a taste for human flesh; if you have a cite, I would like to see it. Sharks are pretty opportunistic feeders, I think. A shark might well eat a human body if one happened to be floating by but I doubt it would make that shark hunt humans preferentially.
After a while, the screaming and kicking probably wears off a bit.
