Goldhagen and the Pope

In Goldhagen's article regarding Nazi Germany and Pope Benedict the XVI, he compares the Pope's mind-set to the mind-set of Nazi Germany.  Even though Cardinal Joseph Ratzinger, also known as Pope Benedict the XVI, was raised in an anti-Nazi family, he joined the Hitler youth.  Through the article, Goldhagen is comparing the relativism of Nazi Germany to the relativism of Pope Benedict the XVI.  As relativism relates to Nazi Germany, Hitler believed that only one type of race should exist in the world.  Therefore, concluding to the Holocaust and the mass-slaughter of everyone who was something besides a white, blonde hair, and blue eyed human being.  On the other hand, as relativism relates to Pope Benedict the XVI, he believes that Catholicism is the only way to God and his Heavenly Kingdom.  Therefore, was the Pope as corrupt as Hitler from a theological point of view?
