Mussar zogger- If we lived for olam hazeh, you have a question. But the primary world is thie Olam Habah. Do you think they are not getting just and appropriate reward for following Daas Torah whee they are now? Is Hashem punishing or rewarding them for listening?
We need to see the picture from Hashems perspective. I am sure that if we were able to communicate with any of those neshamos, they would choose to stay rather than come down. Like the story of the 2 year old killed by terrorists who came to his mother in a dream.
With Emunah it is all acceptable as is.
