I see what you're saying (I think), but how has mankind created the physical and mental pain caused by natural diseases, natural disasters, and loss of loved ones?
Maybe because they are only natural disasters in relation to ourselves. They are natural processes. Does the giant cyclone bigger than Earth that twists in the atmosphere of Jupiter qualify as a natural disaster? No. It is not a disaster if it does not cause human suffering. If I walk onto a freeway and get hit by a car is it God's fault? But we have lost the ability in our fallen state to see the oncoming traffic.
