This is a wild and flailing rant, with which I mostly agree, (I think), except your postulate that “there is no cure”
Just as God has said the sins of His Nation Israel are “incurable” :
Jeremiah 30:12-14
"For thus says the LORD: 'Your affliction is incurable, Your wound is severe. There is no one to plead your cause, That you may be bound up; You have no healing medicines. All your lovers have forgotten you; They do not seek you; For I have wounded you with the wound of an enemy, With the chastisement of a cruel one, For the multitude of your iniquities, Because your sins have increased.
He then actually does offer The Cure!:
Jeremiah 30:17
For I will restore health to you, and heal you of your wounds,’ says the LORD, 'Because they called you an outcast saying: “This is Zion; No one seeks her.”
God Himself is the cure.
You also said:
This prophecy is unfounded, unscriptural, and inflammatory. Nobody is “killing”, even though sin surely is.
I know that you ascribe to the teachings of Terry Pratchett, and you publish his fantastic words of his fabled specter “Death”:
“You need to believe in things that aren’t true, how else will they become?”.
In this quote, “Death” is tryng to convince Susan that things like justice, mercy and duty do not really exist. But they do exist, in an Eternal Person, Jesus. And they do exist in all those who He has called into His body. Not because we believe in them, but even though most don’t. All your raging against the body of Christ will not erase the mercy and justice regularly promoted and fought for by God’s through His ecclesia.
I hope this is understood in the Spirit in which it is offered.
Peace
