You might want to prepare yourself for a few extremely rude awakenings. God gives life, and He can take it in any fashion He deems fit. I would never personally make the judgment that the Holocaust was indeed "attributable to a divine curse" but, generally speaking, God is at liberty to bring divine judgment upon whomever, whenever, and wherever it seems right for Him to do so. For me to believe otherwise would seem dangerously akin to preferring sentimentalism over truth.
As humans, we tend to value temporal human life and health above all, all too often including righteousness, eternal life, and the safety, security, and harmony of God's universe. But we "wrestle not against flesh and blood, but against principalities and powers of this dark world and against the spiritual forces of evil in the heavenly realms." We see what is recorded in pictures, moving and still, but were the curtain rolled away and we could see the supernatural, the image would be much more complicated to behold. There would appear "hills full of horses and chariots of fire all around" as they did to Elisha and the perplexed servant. God had His 7000 there the day the picture was taken.
In the end, there is no shame in ending up in a mass grave ditch. Only in being barred from ever rising up from it. Or in ordering its digging.
