There are alot of questionable things doctors do, but they all can be considered doing something "positive" for the patient, i.e. "do no harm"
Harvesting organs as a form of execution does not pass the "do no harm" test, not even close.
Only if the "patient" is still alive......... Uuummmm........
The concept from Strolling as I understood it would be to anesthetize the person, remove said organs, and then let them expire while under.
They would be "alive" during the extraction and then left to die.
Never heard that one before but considering what some of these animals have done to other people....... Not sure I have a problem with it in those specific cases. But that's just righteous outrage speaking.
