Concerning his motivation to destroy the stones, Thanos stated that:
The universe required correction. After that, the stones served no purpose beyond temptation.
I am wondering who is being tempted here?
Is the temptation Thanos's own? Or is it temptation from outside forces? I suspect, given the context of the statement, that the temptation is from outside forces (e.g. somebody wanting to use the stones to undo what Thanos had done: the snap).
Which leads me to ask - is there anyone powerful enough in the MCU to have wrested the stones from Thanos, now that he had all 6 and was effectively omnipotent? Is Captain Marvel plus support from the other surviving Avengers powerful enough to take on Thanos when he is wielding all 6 Infinity Stones?
I suspect that nobody could have taken the stones from Thanos, but then I am puzzled as to why he would destroy the stones (the universe could possibly require correction again, after all the human population has doubled in the last 60 years; halving all life with a simple snap does not ensure that it will remain that way forever).
So all of these questions flying about in my head is making me reconsider Thanos's motivations for destroying the stones. Something tells me he could have easily kept hold of them without much quarrel, given the powers that they bestowed upon him.
Is there any in-or-out-of universe information that expands further on the motivation Thanos had for destroying the stones?
