You raise very valid points. Those are absolutely concerns I might have too if I actually believed in a god - am I following all the rules, am I good enough to get the good ending etc etc. It's good to not have illusions that a higher authority will take care of the problems of this world and actually work to fix it ourselves.

And in moments of hope, when things are improving, it seems we as humans are succeeding in that. But looking at the world now, those moments seem fewer and fewer. It gets harder to keep working on improving, or even thinking that we can improve.

But I don't want to just say injustice is natural and bad things will always happen and cannot be stopped. Individually, yeah - there will always be people who do things that are not good. But on a societal scale? A better world is possible. In this aspect, having a belief in a higher authority, one you believe will be "good" and "just" can help centre you and give you hope. I guess, spiritual rather than actually religious. But I can't even believe in that.
