Sometimes I also think about, if I were God what would I create? Would I make something that exists in a very specific way, perhaps mankind could be perfect, all identical genes, billions of twins. Though without variation these people might risk death in am ever changing world. The only way to remove pain and suffering would be to create us all as Gods ourselves. But I'm not sure that there really could be multiple God's, all infinitely existing at the same time.
Sometimes I consider that the world has to be this way. A world without pain would be a world without freedom, without individual minds. If we consider a scenario where a child is starving and someone makes a choice to feed that child, it would be a beautiful thing. But could a world exist where no one ever was hungry? Maybe this world would have infinite food, on a planet of an infinite size?
For a world to exist without pain, the world couldn't exist at all. So what would creation look like, if there were no suffering?
Often times our suffering comes from failed expectations. I expect a slice of pizza to have a certain taste, I bite it and it's not that good. I then suffer.
In a world without suffering, do I no longer taste? Does pizza taste infinitely good? How could I bake an infinitely good pizza? I wouldn't bake it at all, there would be no cooking at all. Then I would simply suffer because I could no longer enjoy cooking or baking because the pizza was already perfect right out of the freezer.
To truly remove suffering, I'm not sure that creation could even exist. And therefore perhaps suffering must exist by default.
