If that's the case, then we have no clue what caused the death of 99.99999% of the people who die.
How many people do you know of who have had autopsies performed on them after they died?
None was ever done.
So? No autopsy was performed on John Paul II. Or Paul VI. Or Bl. John XXIII. Or Pius XII. Or Pius XI. Or Benedict XV. Or St. Pius X. Or Leo XIII. Or Bl. Pius IX. Were they all secretly poisoned in your opinion?
JPI's dead body was green.
No, it wasn't. Paul VI is the Pope whose body famously took on a greenish tinge while he was lying in state.
That doesn't occur with a heart attack.
I'm sure you're a medical doctor with a Ph.D in forensic pathology, but please tell us simple folk how a heart attack prevents a corpse from rotting.
Exactly what does that have to do with the price of tea in China? You folks get more and more bizarre in your attempts to support straw men.
AGAIN, produce the autopsy report which states JPI died of a heart attack. If you can't, stop making this false claim.
And yes, he was embalmed. His corpse was not rotting.
