Nowadays, it's rare to see questions not answered. I wouldn't even say "not answered DIRECTLY". They are simply not answered.
The fear of losing reputation, friends, etc., that is pathetic for a man of God.
Only through Christ is one saved. I am not surprised if there are "good" holocaust Jews who got saved or "good" holocaust Jews who weren't saved. Because we frequently do not label terminologies accurately. However, I can be very sure, that all those "good", "innocent" Jews who died of holocaust, will be shown their past lives before God and admit that they weren't that good nor that innocent, and it is going to be so revealing that they are going to satisfyingly accept what they deserve.
