Marcia, first, no man can be born morally upright, for uprightness cannot be predicated apart from a righteous choice. Adam was not born righteous, but rather with capacity for righteous, which obviously he did walk in for some time even with Eve.
God has made all my children ‘good’ as well Marcia, but as was Adam were neither created sinful or holy. Those following Adam certainly were born physically depraved with depraved natural sensibilities in a manner Adam was not, but still did not sin until reaching the age of accountability yielding selfishly to those propensities. In the same manner all others have sinned as well. Although they might not have sinned after the same similitude as Adam, they all have sinned just as Scripture states they have. Not because of Adam, nor the nature they were born with nor any other force or coercion, although that nature is a formidable obstacle and clearly serves to enhance temptation, but rather by willingly yielding their wills in accordance to selfishness apart from force or coercion.
