That “no one is righteous” is a quotation of Old Testament passages about spirit beings. It is not a categorical denunciation of humans. The human is loved. John 3:16

Much of the attack you’re trying to regard as a critique of yourself is about spirit being. The OT has a complex narrative of spirit “rulers” going bad. The prophetic texts are largely about that subject.

Then Jesus came, sets you free from their slavery, loves and helps you develop. That’s the story.

You are not critiqued or judged, or to do that to yourself. As a Jesus-follower, you love others, and that has self-love as its foundation (cf. Mark 12:31).
