Think about the modern, vain woman, and how they often displays themselves as cute, good and well-mannered on the outside, but on the inside they end up having the most unsavory beliefs (you can see this most prominently with how they treat short men - as if they're sub-human). Lucifer *displays* HER(him)self as an angel of light (soft, fragile, innocent exterior), but in actuality is the very embodiment of evil (dehumanizing of the other). "Punch a nazi", "kill all men", blatant disgust at being approached by a shorter male and deriding them mercilessly.

It's so obvious. I can't believe it took this long for me to come to this revelation.
