Global Pandemics make the Shoah look like child's play

Good grief. I was cruising the web for disaster porn and I found the following facts about global pandemics:

1300s Black Death - Killed 30 million + 

1800s Cholera - Killed 50 million +

1918 Spanish Flu - Killed 20-100 million

1957 Asian Flu -Killed 2 million

1968 Hong Kong Flu - Killed 1 million

And these deaths are not pleasant.

So why does God do this? Millions of people killed for what reason? Loshon Horoh? I think that people who can't believe in God because of the problem of evil are actually more moral than believers. These kind of atheists are so bothered by the problem of evil that they just can't ascribe this behavior to a God who is supposed to be all good and all powerful.

I personally like to believe in a personal God, espcially One who looks out for me personally. But the problem of evil is very difficult to deal with. Most people don't really think about it to any degree of seriousness, and therefore are happy with the usual trite answers.

I'm not sure what I would think were millions of people to die in a pandemic. Could I still maintain my belief in an Omniscient and Omnibenevolent God? Would I be satisfied with the 'You can't understand God' answer?

With respect to the Shoah, one 'answer' that always resonated with me, to the question of 'Where was God during the Holocaust', is Heshcel's famous response: 'Where was man during the Holocaust?'.  But with respect to pandemics - 'Where was God during the 1918 pandemic?' Response - 'Where was the Tamiflu during the 1918 pandemic'? doesn't work so well.

I don't have any good answers here. All I can do is daven to my personal God and ask Him personally not to test me in this way.
