Nobody needs an old story book to know how to be a good person. The issue lies not with a lack of bibles, but with a manufactured lack of social cohesion. Years of propaganda against socialism and unions have lured a big part of the US population in a trap of "hyperindiviualism", where you are preyed upon if you don't play the same game of "me first".

Fixing this needs politicians that come from the people and work for the people, but the rich part of society has undermined the (sadly bad designed) process where such people can rise up into positions where they can make decisions. The common folk is under permanent attack by the 0.1%, and many of them (see MAGA) don't even recognize from where the systematic violence they are experiencing comes, because they get fed that socialism is the thing that oppresses them.

If you add religion to this cocktail, it acts like adding a hypergolic fuel into a house fire. It gets instrumentalised to create an in-group and to define an outgroup. Religion is not the way out.

The US are in quite a pickle, and from the outside i don't see many peaceful ways out of this situation.
