Well, those accounts weren't written, or even dictated by Eru Himself, so we're only getting opinions here
I still don't think we can get a clear enough sense of Eru's personality - & I'd still ask whether he has a 'personality' in the psychological sense, or an Ego or a superego, or an id - does He have a 'Self' in the Jungian sense?
In other words, can we use psychological terminology to 'psychoanalyse' Him? Can we diagnose Him as suffering from a human personality disorder? Even if we could interpret some acts in psychological terms, it being impossible to (taking the position of a creature within Middle Earth) concieve of the mind of Eru. And if we're analysing Eru as a character, we're really analysing Tolkien's concept of God, & psychoanalysing him - why would he come up with a God that behaved in a sadistic way (if we think He does).
