> The story of Abraham is a way to break that spell
That's an extremely generous interpretation. You say the story is about breaking the cycle of pernicious child sacrifice. But there's nothing in the story that supports that view, you just said it because it's the most palatable interpretation of a straightforward story: Obey God, and he may give you mercy (not having to kill your kid). And you conveniently ignore Moses killing all the first-borns.
> Human sacrifice and ritual cannibalistic wars of genocide is the natural condition of humans as a species
There is no "ritual" wars without religion. Religion is what is natural to humanity, as it develops in every culture without fail. Whether you worship Jesus or the Sun, the belief in an afterlife if you follow the rules the last generation handled to you is what leads to terrible deeds, because you can justify anything.
> The story puts an effective limit on the level of worship
No, it doesn't. Many innocent people are sacrificed or ordered to be killed throughout the verses. Jephthah sacrifices his daughter. Saul is asked to kill women and children.
> Seeing as the Bible is a collection of stories that where told for thousands of years before being written down
If by told for a thousand years before being written down, you mean edited, distorted, and mistranslated to the convenience of whoever was in power at the time, yes.
