No. They helped put them in power.
As a 21st century man looking back at 20th century men and at the times and place they lived in, I believe I see that by the Vatican's actions they followed their Adamic nature to save their own skin while ignoring "social justice" for the Jews.
Currently, the RCC is after what they have always coveted, Jerusalem, and their great concern is "social justice" for the dispossessed Palestinian Islamic terrorists, only because it serves their political needs for leverage against Israel to wrest away the object of their covetousness. In either century, the Jews draw the short straw, as is their fate until they come to recognize their real messiah.
If choosing sides invokes error, I'll err on the side of the Jews, and let the RCC and the PLO rail against me.
Mussolini and Hitler are reflections of the people who put them in power in their time, just as Obama is a reflection upon the majority of people in this country who voted for him. Who is drawing the short straw now? Both Christians and Jews, and that was foretold by the prophets of God, and His Son.
