They were demons posing as gods..according to legend.<quoted text>
If this deity so hates "evil", then [WHY] does he allow it to continue...or even exist.
I see a totally different equation here.
It is the "true self" of the deity presented... when the deity was found to be unacceptable by the masses....and "satan" was invented to deflect the deity's true attributes.
YHVH is "Enlil" who "hated" mankind.
Enki(who created and loved mankind) was construed by religionist priests as the serpent(the symbol of the doctor/geneticist), and the evil one.
Actually it is completely contrary to what you have been taught....and even ~that~ is incorrect.
It is known that "Enki" brought civilization(mankind) to this planet well over 70,000 years ago.
Most of the false gods laugh at you all who deny the True GOD.
