[Avengers 3/4 SPOILERS] What if Thanos failed in a specific way...

So, Thanos goes ~3 weeks (I apologize, I don't remember the specific numbers, but it's not too relevant) before destroying the stones, then accepts his death. 

What if, after some amount of time, it could be *proven* beyond a shadow of a doubt that halving all life did *not* save people with abundant resources, but screwed over or led to the death of more and more life? 

We see in Endgame that humanity (and presumably other civilizations) are learning to live with the snap and move on as much as they can, but let's pretend things went much more negatively. 

Like, as if the condition of life and number of living things just kept going down and down, and there's never an upswing that Thanos can claim happened because of the snap? And in a material, physical way, not people being distraught over the deaths (since Thanos obviously doesn't care about that). 

Is there any length of time after which Thanos would accept he was wrong? Or will he always believe that *eventually* people will be thankful for the snap? 

[hypothetical situation in which Thanos continues living indefinitely and no one ever discovers a way to undo the snap]

Thanos was a fanatic to his own cause. He was incapable of accepting that he was wrong. No amount of logic will convince someone who has made up their mind so thoroughly. As Issac Asimov said "Against stupidity, the gods themselves contend in vain."

This is why in end game that when he sees the universe will never accept his "gift" as a good thing, he decides to remake all life in the universe in a form that will believe his insane, flawed logic.
