Re: "So what? does that excuse him being a member of the Hitler Jugend? "
No.
In order to make you happy, the little frightened Germany boy should have turned in both of his parents to be executed, maybe his older brother as well, and then told the SS that he refused to join der Hitler Jugend on moral grounds.
Then he too would have been executed by guillotine, and then you would be self righteously excoriating someone, anyone, from any part of the world and from any time period in history, for their unwillingness to be put to death for circumstances about which they had no understanding and over which they had no control.
To tell the truth, Ha'Shem could have done a lot better job in creating the world, for he could have just killed everyone on the planet whom you find guilty of not meeting your personal high standards of conduct and morality.
Then there would just be you, Ha'Shem, and maybe another person or two inhabiting the planet.
Finally, Redemption!

I am overcome by sanctimonious righteousness now and must get back to my list of those Jews who must be exterminated for their weak observance and their weak faith.
The children of course will also be dispatched, as they are equally guilty of anything their parents might have done or said.
You know...one thing that's really hard to understand...Why did G-d even bother to create a bunch of Europeans, Nips, Slavs, and Chinamen is beyond me, because none of them are Jews and they certainly are at best apathetic to Jews, so why doesn't He just kill ALL of them already? That goes for all those Hindus too - why they hardly ever even think about a Jew and act as if they have their own culture, history, and religious traditions.
