Kinda off-topic theme but the Supreme Deity:
- Burned and massacred and entire city because she was trolled by a little girl.
- Killed her own daughter and never cared for the fact that she suffered for 3.000 years.
- Is responsable of the killing of innocent civil demons who didn't partcipate in the war. Basically gave an ideology of discrimination to her clan.
All these things are things that the Demon King did as well. Both gods are responsable for the bad things that happened in the whole series.
Sure, Nakaba can make her show up and show that her true intentions were actually good. But so far, what we know of the SD is thanks to the DK, they're practically partners in crime. Calling her "good" doesn't make much sense by knowing all the killing she's responsable for.
She's basically the second main antagonist of the whole curse subplot.
The "is she for villan material?" is a different debate, though.
