How does any of that alter that we are born guilty and condemned (Ro 5:12-21)?As I said previously, I agree that "Scripture is the arbiter on this."
However, I must disagree that it's no more complicated than your post allows. For example, in the Scripture we learn two more things about responsibility your post here did not cover. (1) In Romans 1, the knowledge the truth suppressors inevitably possessed was a standard for their responsibility (note the judgement language at the end of R1 and the statement "so they are without excuse"). (2) We can visit the terrible account of Amnon and Tamar in 2 Samuel 13. It is a truly revolting and tragic event. Clearly, the context points out that Tamar was opposed to Amnon's pursuit. But the passage points out a situation of "forcing" (v14) where I think that all here would definitely not consider Tamar accountable or responsible for Amnon's terrible actions. She clearly did not want to do what Amnon wanted.
Again, my point above is that Scripture fills out the issue a bit more. I think that your post is a good start in dealing with how Scripture addresses the matter. The other passages of Scripture, addressing the issue of responsibility, are not "window dressing." And certainly, the Scriptures I just referenced are not the full picture either.
At any rate, thank you for sharing your thoughts in the post quoted above.
That being the case, everything else is window dressing.
