The argument is not that God "DID" these things (although a strong one could be made in that direction). The argument is that He COULD HAVE PREVENTED THEM AND DID NOT.
The physician analogy earlier in the thread illustrates this.
- Someone discovers a compound that would cure all forms of cancer with no side effects
- That person lets everyone know he/she has discovered it
- That person also declares he/she will NOT share this discovery with the world.
- That person also decides to go to as many cancer wards as he/she can, including pediatric cancer wards, to watch patients die of the disease he/she has a cure for.
Such a person would be pilloried by the public. What could be more evil than this?
