To be fair the idea of Satan hadn’t been invented yet and in Genesis God is just one of many gods also that God isnt all good.

It gets confusing because the continuity errors from retrocons. Highly likely the original story was a group of gods created the world, one of those gods created a tribe, and another god decided to mess with that tribe. Later on the group of gods got condensed into one and the god that put the snake in got demoted to evil angel status.
