Hitler used the Jews and other sections of society as scapegoats, blaming all the problems on them. To Germans at the time Hitler made sense, he united everyone by providing explanations for Germany's problems.
He used pseudo-science and claimed that Jews were (genetically) a race in order to justify eliminating the Jews.
"The Final Solution" was a euphemism used by Hitler in decribing the systmatic extermination of six million Jews.
The purpose of the Hitler Youth was simply to indoctrinate young Germans so that they would grow up to be good Nazis; this organization did not have the task of hunting for Jews.
The Nazis 'sent the Jews away' in order to use some of them as slave labour and to kill them.
You're thinking of Eichmann, Hitler would not have bothered about such things.
