The Souls of those Who died in Nazi Concentration Camp?

Q Where did the souls of those who died in Nazi concentration camp go? To hell, purgatory? Or heaven? Another Q: If Moslem is professing a false religion and they go to hell, what about all the Jews? Are Jews Christian?(Bridget McDonald)

A  Every man must be converted to our Lord Jesus Christ in order to go to Heaven, because our Lord Jesus Christ is the only Saviour of the world: “I am the way, and the truth, and the life. No man cometh to the Father, but by me” (Jn. 14:6).

 This is true for Jews, Muslin, Buddhists, etc. Now though the concentration camps were horrible places as far as this life is concerned, it was also the place of many graces: it was the place where St Maximilan Kolbe reached the summit of his holiness, and many others good Catholics did a holy death there (the father of Archbishop Lefebvre died thus in a Nazi concentration camp).

 Those who were sinners before they went there had occasions to see these examples, and it is certain that a good number of them repented and embraced the faith (if they did not have it before) or returned to a good life (for Catholics) and carried their cross with Christ: this is even true for some Jews. Indeed some of them were already Christians before they went there (think of Edith Stein, Jewish of race, became non only a Catholic, but even a Carmelite and died in the Auschwitz concentration camp). The Cross is always an occasion of grace.
