leomoon, I think your description of Satan in Jewish belief is basically correct.
First of all, whatever else it may be (scripture, the Word of God, a fable, a history, or.... ) the Bible is a work of literature. Some of it like the Psalms were written as songs or poetry. The Song of Songs is love poetry. The Bible includes parables, meant to instruct but not to be understood as actual facts.
In this context, Satan can be understood from a biblical Jewish perspective. As you put it, the "evil impulse" is distinctively human. The "adversary" is a metaphor from whatever turns people away from God. Maimonides, the great medieval Jewish scholar, thought the book of Job is an allegory or parable.
Of course, Judaism has existed in many different lands for many centuries. Various rabbis thought that Satan and other demons were real, notably in the Kabbalah and chasidism, but this isn't the majority view.
As you point out, humans are capable of all kinds of evil. We don't need to hypothesize a supernatural Satan to explain it.
I'm so glad to meet another human being, besides my husband & myself, (over 70 years I might add), who says out loud, having been "around the block" so to speak both in church, synagogues, and any other religious study that SATAN is a man made concept. (not sure about g-o-d yet), the jury is still out.
No one can devise like man (his mortal soul) can, the hatred in their hearts and express it outwardly, like humans can.
Even the other animals on the earth do not go out purposefully without it being instinctual to kill, main & torture.
Only the human animal does this. Sadly, the human animal demoralizes his very immortal soul this way spreading hatred rather then love and acceptable, tolerance & the age old "7 spiritual virtues"
https://en.wikipedia.org/wiki/Seven_deadly_sins
Seven deadly sins. According to the standard list, they are pride, greed, lust, envy, gluttony, wrath and sloth, which are also contrary to the seven virtues. These sins are often thought to be abuses or excessive versions of one's natural faculties or passions

For me the 7 Virtues are what my life aspired towards nothing else really. Everything else is "outward" stuff.
Marcus Aurelius did not need a church to tell him about the 7 Virtues, and practiced them in his life and managed even in his "time, culture & place" as a Stoic to embrace what was right and holy. He didn't need a priest or a whatever someone other then his own higher conscience we ALL have somewhere inside, whether buried by us or brought to light of day.
Marcus Aurelius was a man who lived by the Stoic laws, which so capably go into making a virtuous man. He did this by nature and also by learned practices, all the way from his youth to his dying breath:

No school, no church, no parent, no friend told me about Marcus Aurelius, I simply took to teaching myself along the way at a young age as open-mindedness is available to ANYONE and does not need prompting other then one's conscience (imo)
This link says it best:
Almost every other piece of literature is a kind of performance—it’s made for the audience.
Meditations isn’t. In fact, their original title (
Ta eis heauton) roughly translates as
To Himself.

When I married, I married a man whose mother was so thoroughly brainwashed within the Billy Graham cult and orthodoxy, sending her son & daughter to "Bible School" on the weekends, when he felt they should have been out playing since "school" was not in session.
Seeing the hypocrisy of actions vs ideals held within the pastor's teachings, just turned him off forever.
In a way my mother also came away turned off when during the Great Depression years as a young teen, her grandmother's church did not give them the help or food the family asked for - That was IT for mom, she turned away, much to the chagrin of her Quebec Catholic raised mother. Mom sent us to church, but she herself would never step a foot into except for marriage or funerals,
and seldom, maybe twice in my lifetime.
Yet, she sent us to the Catholic school down the street, (not far from Nancy Pelosi's own school and church) although I am 10years her junior)
Mom felt she was taking care of her promises she made to raise her children the best way she knew how, the way she herself was raised.
I've mentioned this before, that my 9th house of conception is ruled by Pisces/Jupiter.
Dad was agnostic, and taught us about evolution, never buying into nor attending any church or otherwise. So it was a real eclectic mix we had for which my sister & I were grateful.
I still recall the incense the priests would burn on Sundays and holy days, and the bells that would chime. I miss the Easter services with the wonderful choirs of Alleluia. These things I miss and tried to find it again in the Episcopal church I attended once as mentioned.
Other then that, I don't need nor want their preaching. I believe I put the photo early on in this thread telling Missionaries to PLEASE stop trespassing on my porch and door trying to "save" me.
I KNOW they mean well, but I consider then to be brainwashed.
Which reminds me of my daughters., the middle one is VERY literal minded, A Sun Capricorn who shares the birth chart of Congresswoman Katie Porter of Calif. They are what is called "astro-twins".
When her paternal grandparents took them to church with them once upon a time, I recall saying to my kids, "be careful, watch out for brainwashing",
....and she told me years and years later, "I thought it was a LITERAL warning, that they'd "wash my brains" when I saw thee room with the bathtub for baptismals and wanted to avoid THAT room!
I once visited the Jordan side of what UNESCO decided was worthy of being called the possible Baptismal site of John. Both Israel & Jodan demand that claim for themselves. As the crow flies, not "that" far from the land they are known to have trod and John grew up. Its called "Bethany on the Jordan"....and I had a deja vous moment or two going there. It was a wonderful overall side vacation from Egypt. I wanted desperately to go to Israel in my lifetime, and my husband absolutely was appalled by the idea. He LOVED Egypt immensely however, the people, the culture, the land. I figure, he lived there as a Roman once or twice.
Anyway, I made a DEAL with him, "IF he goes to Egypt with me one year we take a side trip offered for 5 days to Israel - THEN I will go with him the following year to Egypt and take the side trip to Jordan and he can see Petra and the places that his movie hero "Lawrence of Arabia" was filmed" He agreed!
We saw the best sites from both this way. But my fav of all was "Bethany on the Jordan" which was btw, given to us carte blanche, because the tour diverted and instead of 2 days at the Dead Sea overnight there, they gave us this!! Talk about Carl Jung's theory - (fate)
Smelling those tamarisk bushes on the way to the site was a spiritual throw back for me:
the word for tamarisk can also be translated as "grove.
