I don’t think goddess means any malice / is in anyway evil. Though what happened to her ended up being sooo cruel, that I wish she wasn’t summoned in the first place!
I think what she means by “THAT early” is, that she knew humans as frail creatures (compared to gods) and that they die easily, but she didn’t knew her fate would take such drastic turns to her doom....
Well, basically society is to be blamed (other than spoiled rotten royals and other greedy aristrocrats, also male chauvinism), where she was basically outcasted and thrown away.
But yeah, I agree, the 3rd life was the worst! She was searching for ways to die, to escape such horror, but with hardly any success! And to think when she succeeded, that the hero had to return that very moment!
It was such a sad-sweet moment of reunion and farewell, as she said she was glad to him ok
