That mankind has a sin nature is clearly taught in scripture. Romans 7 gives an adequate description of how it displays itself, even in those who are "good," but what, exactly, is the sin nature? I think it could be described in terms of the bondage of the will accurately enough, but where exactly did that bondage come from and how does it work?
I stated before that mankind was made in the image of God, but in ignorance (innocence). That condition was called good by God, despite the claim I've made that it was not his ultimate aim, nor will it be our condition in eternity. Our higher abilities (like will, choice and creativity) were made complementary to God's because he wanted mankind to live on his level as his family and friends. Though he is the omnipotent God, scary on so many levels, his aim is to have us be one with him.
What does all this have to do with the sin nature? Well, God alone is good: only he has what it takes to express Godlike attributes in harmony with his perfect will. Only he can manage those things which make up his image. The sin nature arose in mankind when Adam and Eve, despite having the breath of God (a living Spirit), exercised Godlike capacities in opposition to God. Sin is the exertion of will contrary to the will of God.
As a consequence, the breath that God imparted lost its connection with the God who breathed it (spiritual death), mankind was thereby separated from God, cursed, and whatever capacity pristine man had to walk in the will of God was lost irretrievably. Since then, we walk in dying flesh apart from God, godlike to some degree, but anything but like God. We possess some godlike capacities, but without the ability to harness them to "good." We do what we have an urge to do regardless of what God wants: some more, some less.
That is the essence of our sinful natures. Adam and Eve had their life degraded to that level, and at that level they reproduced what would become all the rest of us. They passed on their broken nature as sinners, because it was all they had to pass on. The machinery of our soul cannot function without God being in us, and us being in agreement with him. That disagreement, and the disability that results in being without God is what makes us sinners.
