Well, given that no one knows the true nature of god, I'd say any discussion is moot. I can tell you what I know about God and it doesn't
necessarily correlate with what the Abrahamic religions say.
However, when you bring Satan into the topic and try to make him out to be a "good guy," I think you're going down a slippery slope. Now, I am not
saying that Satan oes not serve a purpose. He does. However, I wouldn't label him "good."
From my own understanding, Satan is basically a tester and a testifier. He will, when "judgment" occurs, testify to the deeds and thoughts of
humanity. In this regard, Satan and God are cohorts, but that doesn't take away from the fact that he has fallen away from the truth and the
light.
Among those books of the Hebrew Scriptures written before 300 BCE, the term "satan" (root word "s'tn") appears often. The word is derived
from the original Hebrew verb "satan" which means "to oppose." The Septuagint translation of the Hebrew Scriptures into Greek was widely used in
the early Christian church. They translated "satan" as "diaboloc" from which we derive our English term "devil" and "diabolic."
The word is used to refer to:
Any person acting as an accuser or enemy. For example: 1 Samuel 29:4: The Philistines were distrustful of David, fearing that he would be a satan.
(translated "adversary" or "someone who will turn against us").
2 Samuel 19:22: Shime-i apologizes to King David. The King rejects the apology, saying that they should not be a satan to each other (translated
"adversary" or "opponent").
1 Kings 5:4: King Solomon is talking to Hiram, the King of Tyre. He says that now that there is neither satan nor bad luck to stop him, he can build
the Temple. (translated as "adversary", "enemy", or "one who opposes").
1 Kings 11:14: God raised up Hadad the Edomite as a satan against Solomon. (translated as "adversary," or "opponent").
A divine messenger sent by God as an adversary: Numbers 22:22 & 32: God appears in a dream, telling Balaam to go with the princes of Moab to meet
Balak. But when Balaam sets out the next morning on his donkey, God is angry with him for some reason, and sent an angel/messenger to kill him. The
donkey saw the angel and took evasive actions. The angel was invisible to Balaam, who beat the animal. The donkey asked Balaam why he had beat her
three times. Balaam, who doesn't seem to realize that a talking donkey is an unusual occurrence, replies. The angel then appears and explains that he
has come as a satan to kill him. (translated as "one who opposes, "withstand," "adversary")
a member of God's inner council; a type of chief prosecutor of Heaven: 1 Chronicles 21:1: Satan, "a supernatural evil emissary," acting on God's
behalf, has influenced David to hold a census. The census is taken, and God is angry for an unknown reason. Perhaps God does not want humans to be
aware of the strength of the army. God then offers David his choice of one of three punishments: a 3 year famine, 3 months of fleeing before his
enemies' armies, or a plague throughout Israel. David selects the plague and God killed 70,000 men (and presumably a similar number of women and
many tens of thousands of children). In 2 Samuel 24, the identical event is described. However, this time, the text states that God influenced David
to hold the census. Even though God had incited David to enumerate the men of Israel and Judah, he was still angry that it was done and punished the
Israelites with a plague. The writings in 2 Samuel are believed to be the original account; 1 Chronicles came later. It is believed that when Samuel
was finally edited (circa 560 BCE), the editors thought that all supernatural actions (good and bad) came from God. When Chronicles was written over a
century later, (circa 400 BCE) the author viewed God as operating indirectly through his helpers.
Job 1 and 2: Satan is described as one of the members of the court of heaven. God mentions that he is impressed at the behavior of Job, a blameless
man who has lived an upright life. Satan attributes Job's commendable behavior to his good fortune and says that Job would soon curse God if he had a
string of really bad luck. God decides to conduct an experiment with Job; he instructs Satan to destroy all that Job has: kill his animals, murder his
employees, and murder his innocent children. But, even after these disasters, Job still does not curse God. So God instructs Satan to up the ante by
returning to earth and destroying Job's health. Here, Satan is portrayed as a servant of God whose task it is to dutifully carry out evil deeds at
God's instruction.
Zechariah 3:1-7: Satan is again portrayed as a member of God's council. Here he objects to the selection of Joshua as the high priest.
Conflicting messages
Now, obviously, judging by some of those scriptures, there are some conflicting messages about exactly who or what Satan is.
