I'd even argue Kasyrra is less evil because she has no moral quandaries about what she does. She physically cannot. All these other people are capable of having a conscience, but act against it anyways. If anything Kasyrra is absolutely correct in that she's just liberating this world by freeing people of their conscience. They were gonna do it anyways, why bother with pretense?The coming of Kasyrra is just adding one more evil in the cesspool that is COCII setting.
All the gods are pricks too. Mallach has his followers grooming children, Keros fucks with people and doesn't equivalent exchange whenever he wants, Lumia lays siege and conquest, Nvaera - or whoever - just sits there reading while the world burns... they also aren't even gods to begin with and yet justify their bullshit as "deities". All of these entities are significantly stronger than Kasyrra and they have no qualms with fucking with mortals... but they do nothing. There is no justification given on their part to do nothing solely because they'll fuck with mortals on their own selfish whims.
Savin is a terrible writer and this is the world he created because of it. /shrug
