Satan is not the "god" of evil. There is an angelic hierarchy in the scriptures, and we also are part of a hierarchy:
Pss 8
[3] When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained;
[4] What is man, that thou art mindful of him? and the son of man, that thou visitest him?
[5] For thou hast made him a little lower than the angels, and hast crowned him with glory and honour.
[6] Thou madest him to have dominion over the works of thy hands; thou hast put all things under his feet:
[7] All sheep and oxen, yea, and the beasts of the field;
[8] The fowl of the air, and the fish of the sea, and whatsoever passeth through the paths of the seas.
Heb 2
[6] But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man, that thou visitest him?
[7] Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands:
[8] Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him.
[9] But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
[10] For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings.
The psalmist's choice of the expression "THE son of man" may refer to Moshiach, as a unique individual. I will have to check this:
Psa 8:4 (8:5)
מה אנושׁ כי תזכרנו ובן אדם כי תפקדנו׃
I though so... a more appropriate translation would seem to be A son of man, not THE. (There's no "ה" prefix, or direct article). Without prompting from the NT or Enoch, then, the scripture simply says
"What is man, that thou art mindful of him? even a son of Adam, that thou visitest him?
Bunny trail over; back to Satan. In Job, he is called a "son of God":
Job 2
[1] Again there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD.
Despite the protestations of Trinitarians here, being a "son of God" indicates that one is definitely NOT God, but one of his creatures. For cross-reference, note:
Luke 3
[37] Which was the son of Mathusala, which was the son of Enoch, which was the son of Jared, which was the son of Maleleel, which was the son of Cainan,
[38] Which was the son of Enos, which was the son of Seth, which was the son of Adam, which was the son of God.
Satan was therefore not "God", but a creation, ranked somewhere in with the angels and men. Some men and other dignitaries were referred to in scripture as "elohim", a term usually applied to God; and indeed, the false gods of the pagans were also called "elohim". Nevertheless, the scriptures are emphatic that none of these, to the extent that they actually existed, was of the status of YHVH:
Exodus 34
[12] Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee:
[13] But ye shall destroy their altars, break their images, and cut down their groves:
[14] For thou shalt worship no other god: for the LORD, whose name is Jealous, is a jealous God:
"Uniting with the world" is not an option for Jews. When they have failed to heed this of their own, the goiim (non-Jews) have been all to eager to set them straight.
