The only people that ever told me that the world should be without suffering had a religious agenda to sell.
Personally I don't get caught up in trying to categorize things as good or bad, they just are. I accept that the world is what it is and I can't change most of it. This frees me up to focus on the things I can change, and to do what good I can without getting bogged down with things that don't matter.
I also couldn't speculate much on what a perfect suffering free world might look like. Our universe is intrinsically disorderly, and a permanent state of stable perfection is unimaginable in the context of the universe that we live in.
It's also difficult to speculate on what id do were I God, since I expect omniscience would give me a bit of a different perspective on things.
Edit:
Theists SHOULD be the ones defending themselves, because they're the ones making outrageous claims without evidence. They also seem to be incapable of providing a description of god(s) that is both internally consistent and matches with observable reality.
