Judaism is about setting an example for character. It has nothing to do with a deity, this is just how you get the scared idiot masses to not act on their impulses.

Judaism is about Yehuda and how he treated his brother when the others wanted to murder him out of spite. This is how Joseph came to be in Egypt. Imagine how Levi felt about Yehuda's betrayel...and what if he had not?
