Not to derail this thread any more than it already has been, but to address that "God's will" issue from a purely Christian perspective... and hopefully I'll keep it nice and short.

God's loves every man, woman, and child on the planet (yes, and even those crazy astro/cosmonaughts
off the planet!), and does not want even one to perish (2 Peter 3:9). So I can say with assurance that the Holocaust, for example, was not God's will.
However, He also has granted us free will, even when we choose things in opposition to His will. This shouldn't be that hard to comprehend, as many families operate this way. "Son, I'd really prefer if you'd stop hanging out with that gang - they're just trouble. But I'm not gonna force you; you're old enough to make your own decisions." So just because something's not His will, doesn't mean He's gonna force the issue.
There is also the matter of things that God allows to happen, in opposition to His will, things which He then turns around for good. In our example, out of the ashes of the Holocaust, the state of Israel was born.
Anyway, I hope that helps some of you understand these things.

Now, back to your regularly scheduled bickering.
