were in a different category from the rest of us. They had free will to choose good or evil because they had not yet become sinful by nature. The only reason someone who has been born again can sometimes do actual good (not sin) is because the Holy Spirit enables. Our flesh still has the sin nature. This is the constant war Paul talks about as between our spirit and flesh once we've been made alive in Christ.
I would say that we are responsible for our actions and choices because from our perspective we have free will, but from God's perspective we are completely helpless to do anything except what He wants us to do. His Spirit moves both believers and unbelievers to accomplish His goals without any deviation. He is eternally the same. There is no shadow of turning in Him (James 1:17).
