Survival in scarcity dictates nastiness with a rival clan, but also dictates goodness towards our own clan whose support is vital to acquire or defend the necessary scarcities.

Man’s nastiness or goodness is not his fault or merit;
They both create the vital coping mechanism to his environment of scarcity.

The core issue in monotheism is righteousness/wickedness.
Righteous/wicked qualifies a person acting or being Good/bad.
In an environment of scarcity, man’s vital strategy for collective survival hinges on being good to his clan and bad to rival clans to acquire or defend resources.
So the creation/elaboration/nurture of both good and bad can only be the consequence of a primary cause: scarcity.
Monotheism “Revealing” such a mental disadvantage in a Creator as to confuse consequences for causes is … revelatory.

What we call “Higher” behavior is elaborated by our abstract mind to ensure survival by an efficient cohesion of our clan.
What we call “lower” behavior is to ensure survival at the expense of a rival, or to prevent the survival of a rival to be at our expense.
So,
Be they our “higher” and “lower” behavior/selves, our humanity and inhumanity, our “Divine” and “diabolic” trends, or any aspect of our Human Nature,
All are created by our abstract mind to ensure survival in an environment of scarcity.

But of course you can always choose to adopt “revelations” which present human nature as:
A messed up image of a messed up supernatural coexistence between two messed up opposite supernatural entities with a messed up relation.

Ultimately, we all think we choose by what we think we know.

Before eating from the tree of knowledge, Adam and Eve had no notion of Good and evil.

They were kicked out of paradise, because the supposed Creator was unable to reason that giving someone free will to choose between two things while having no notion of either, would be the Himalaya of nonsense.

My species should know the following about itself:

-The universe created the ultimate abstract life-form by creating man, but scarcity “programmed” him to this current, ridiculously diminished version of himself.

-Everyone and every community (clan) is everybody’s and every community’s future ally and brother in arms in what will be humanity’s decisive stand against scarcity, whether they realize it, desire it, or deny it.

Violence is formed by the scarcity of nature, and will stay with us as long as we live in scarcity.
