An obvious reason would be the smell. If you bury remains deep underground, they can break down and decompose without emitting foul smells or risk spreading disease. Even buried 6ft down, some animals like dogs can still smell the decomposing remains. In a compost heap they will start to rot and smell with very little to contain it. The smell alone will attract large amounts of insects and other critters, potentially spreading harmful bacteria and disease.
