People who are saying that disease and disasters are man's fault and not god's, how can that possibly make any sense if you believe in a god who is omnipotent?!
I get the (convenient) argument that god created humans with free will, so they are able to choose and make mistakes, but given that god supposedly created everything...
a) Why would he have created horrible diseases at all (however they may be spread by humans)?
b) Why would he have created a world with natural disasters (not by any means all of which are caused by humans)?
c) Why would he let innocent children die of diseases or birth defects which are certainly nothing to do with their 'free will'?
d) Why, if he is an omnipotent and loving god, does he not step in and sort out these dreadful things - even the ones which have been humans' fault?
And finally, if god created the universe and man and all their flaws, then how can any of these things possibly not be his fault?
No doubt it's because god moves in mysterious ways...
