when you try to go to the temple with the daughter in the party, she stops you saying that place is evil
That makes sense though. She is a being born to a god that opposes Qetesh. Nergal & Qetesh HATE each other. Nergal hates her for cheating while if Qetesh didnt before she now hates Nergal for wiping out her followers.
Now that there is even a gleam of Qetesh's power at the Temple, of course you're daughter will say theres something "evil". Its an opposing force that is actively against her own lord. We all think were the good guys of our lives/factions & that those who oppose us must be evil.
She literally thinks that Nergal & there way of doing things in the right & GOOD way because she is born & made from Nergal's will, she knows nothing else... she sees evil in the opposing side when really it's 2 neutral deities in a feuding grudge war. I dont think ether side is "evil"
