Interesting interview I just read that Bono did back in 1988. I especially liked this part:

"I can't understand how people could blame starvation and famine on God. That's to suggest we live in God's world but I don't think that this is the world God created. This is the world we created and sickness is a part of it. I believe that God inspires the minds of men towards medicine and towards advances that can inoculate a whole world. You know, there's enough food in the world to feed everybody -- don't blame God for the fact that we don't share it out. That's something that I got over very early on -- the idea of how could he."
