Lucifer (satan) is depicted as the most beautiful and intelligent angel in all of creation. He is also the biggest jealous rager in all of creation and cannot bare feeling slighted so much so that he begins a complete rebellion against God and righteousness...

Lucifer is essentially what you get with masculine strength and a feminine brain/demeanor. Therefor Satan is essentially a woman in a mans body (well male archangel anyway). And therein lies his depicted evil: feminine narcissism and the desire to supplant God (men) as ruler coupled with masculine strength and energy, even if it will lead heaven to hell.
