I am wondering if there is anything mentioned in LOTR canon that Sauron had once given thought to the possibility that the Valar and/or Eru Ilúvatar may not allow him to conquer Middle-earth, and due to this possibility, that it may not be worth it for him to try to do so.
During the Second Age, Sauron had witnessed Eru Ilúvatar not allowing the King of Númenor, Ar-Pharazôn, to conquer Valinor, so this makes me think that at some point in time Sauron may have spent some time pondering over whether it was worth it for him to try to conquer Middle-earth.
Did Sauron ever consider that the Valar and/or Eru Ilúvatar may not allow him to conquer Middle-earth?
