All the evidence, for what its worth, would say yes - some people are born more-Good than others; some people are, as far back as you go, apparently... well, evil.
In other words, there is a difference between individuals.
But how far back does this difference go? The answer partly depends on how far back we go.
If we each go back eternally, in some primordial essence, then does this Good-evil differential go back to eternity? Do we begin morally different? Or do we all start out exactly the same and the difference arises over time?
This is not a matter of 'evidence'; it is a matter of metaphysics - it is a primary assumption; and it can be validated only by intuition (and the validity of intuition in turn depends on its being the thinking of our divine self - that-within-us which is divine).
If we assume Men are entirely created by God (from nothing/ ex nihilo) and we all start exactly the same; then, because God is Good, this leads to the problem/ paradox of why God would make evil in the world, and men corruptible by it?
If we assume Men are entirely created by God (from nothing/ ex nihilo) and we all start different in terms of degree of Good and Evil; then this leads to the problem/ paradix of why a Good God would make some people more-evil (or more corruptible) than others - and thus more prone to damnation.
But if (as I believe) we all start different, and we have always (in some primordial form) existed co-eternally with God (and therefore, in this independence-from God have the existential basis of genuine free will or agency) - then this difference in Good-evil was already-there before God made us his children.
...Then we can see that the problem of evil is built-in, and evil was not made by God, nor was evil deliberately made possible by God (almost equally problematic).
So, God's creative endevaor is therefore to deal-with the already-existing situation of the reality of evil, and of differential evil; in entities already-with the basis of free agency; while encouraging us to choose first salvation (and thereby join God's family); and then choose theosis (and thereby work towards participation in God's creation).
