Why do you assume that (at least) the Judeo-Christian God is indifferent to anyone?
My grandmother's generation was the last in my family to have been devoted Christian believers.
God's demonstrated indifference in her hour of need turned my father's generation, then mine, then my children's, to agnostics and atheists.
An all-knowing God by definition knew that would be the result.
So among all the Christian sects, only the Calvinists to me have a theology which fits the facts on the ground. If God exists, he has tapped us for the un-elect.
