I don't have a problem with that, provided that the eating is not preceded by any slaughtering.
I can even imagine death rites wherein the deceased is consumed by high-prestige members of the other species as a final status symbol, or fed to low-prestige individuals as an act of charity, or by friends and co-workers, or by one's most effective enemy or rival--maybe as host for a brood of the other's larval offspring.
There are a variety of reasons why cannibalism may become taboo, and plenty of examples in non-cannibal cultures where dead people are allowed to be consumed by other species, whether those are carrion birds, sharks, arthropods, or fungi and bacteria. If your body isn't embalmed or mummified when you die, it's pretty much going to get eaten by something.
Why not get eaten by something that can appreciate your flavor and communicate its satisfaction?
