In the Tales of the Shadows short story, they even say it wasn’t just the tempered people who were agreeing about restoring their loved ones, but untempered as well.
The reason why they summoned her was because they valued that life and didn't think it should be sacrificed. Feelings at the time of summoning are imprinted on a primal so yes she would want to protect life on this planet. It explains why she also isn't taking aether from life on this planet. Instead she took it from the dragon flying by looking for a place to stay.
