Depends how you interpret it tbh. At least in my tradition the focus is on seeing the good, bad, and ugly of history. There's many bible stories that are more cautionary tales than role models.

Now to be fair, there's also examples of God (as portrayed by the writers) being vindictive and harsh. I don't have great answers for that, but I do wonder how much it is seeing through their perspective of the situation and how much it was God. (I obviously come at this as a believer).

As to being the only moral text... I certainly hope it's not, because we've learned a lot since then, and I hope what's considered truth can expand beyond one book.

EDIT: not to dismiss your points, just to say that some of us view it in a more nuanced way.
