The primitive tribal deity in the 'Old Testament' is grotesque from its very inception.

Hellenism grew much more allegorical, with an interesting and useful mythology.

And Hellenists, importantly, were syncretic, accepting other cultures' own symbolic representations of the universal concepts they themselves celebrated.

One of the aspects of Judaism that made it necessarily evil is a foundational/dogmatic demand for hostility towards other cultures/religions.

This also infected Christianity, unfortunately, and Islam, condemning them all to be unethical, not to say murderous, basically by dogma.
