Answer 1

It isn’t the bad part it’s just the incompletely processes part. Also the fact that it has already been partially processed means it doesn’t take as long to break down and therefore the nutrients get into the soil quicker.

But also to your point one of the problems North Korea has is that the people are starving so they use human feces to fertilize but don’t heat it first. This passes down the parasites the “donor” has thereby spreading the parasites even further.
