Of course, she also was childish and selfish from what we've seen, but it is clear that the people cared for her as they had continued to worship her even after a thousand years had passed and that she loved the people as well as she gave gifts to them with generally good intentions.

I'm still confused whether Ishtar was a good goddess that people loved or an evil one who cursed people
