[Shared404]

The first two references use phrasing of "had become" or "have all turned aside" - you cannot become something without first being something else, or turn aside from something without having originally been facing it.

The third reference is stating that no one is capable of perfection, and that no one can earn their way back to God - but impurity only requires that someone not be perfect, not that they have no good.

To be clear, my argument is not that humanity is 100% good because clearly that's not the case. My argument is simply that there is natural good in humanity as well, and most people have more of it as children than after it's beaten out of them as adults.

That is just my reading of course, and I am no expert.
