Guess I don't agree with your premise... I don't think this world, while imperfect, is a place of cruelty etc etc..
When I hear people whine about floods, famine, etc. I feel their pain, but just don't agree that things like that "tip the scales" towards the world being a bad place.
I personally see that every fraction of a second on this earth is a profound miracle... I'm on a rock spinning in space/a product of billions of years of evolution... all for me to sit on the internet and eat Doritos while chatting with people all over the world from my living room. Even if I were to die a horrific death in the next second of my life, I've been living in this incredible world for over a BILLION seconds... seems to me a pretty good deal.
