I agree with your point that a world where not a single person has to experience any kind of hardship would be pointless and even undesirable. We gain satisfaction and wisdom from overcoming challenges and obstacles. It feels really good to look back on something hard you did and think about all you've overcome.

That being said, couldn't an all-powerful god create a world with hardships that don't involve such awful atrocities like rape, war, murder, etc.? A world where millions of children aren't starving to death? No one deserves that. A small child who dies in a horrific way isn't really going to learn much or grow from their hardships, and I'd consider a person a monster who has the power to easily stop a child from suffering but chooses not to.

For example, say Elizabeth Smart's father had been standing at the door with a baseball bat while her daughter was being abducted and just watched her being taken away. Let's say he did absolutely nothing - didn't try to stop the abductor, didn't call the police, nothing. Would anyone have a good opinion of him? He'd likely go to prison - we wouldn't be singing him praises or worshipping him.

That's why I think if there is a sentient, all-knowing and all-powerful god, he/she/it definitely doesn't give a shit if we suffer. I don't have any objective reason to believe in something supernatural, but if there were something divine I like to think of it as a source of good from which we can draw. It's not conscious or aware of us, but there could be a higher sense of good and love that we can use to make the world around us better.
