Judaism is a belief, not a race. You can be any race and still be Jewish. But it was believed at the time that being Jewish was a race because they had a distinctive look (curly hair, big nose).
At the time of Hitler becoming the fuhrer of Germany, Germany was in a depression and Hitler felt that because Jews usually worked in the accounting/banking field that they were to blame.
He believed in a full aryan world but his biggest enemies in his eyes were the Jews. Disabled (mentally or physically imperfect), philosphers, artists, Gypsies and more were also killed. If you're wondering "why didn't he kill black people as well?" well the answer is that there just wasn't that many in Germany.
He moved to Vienna when he was young and made a living by selling pieces or art. In Vienna there was a tradition of anti-semitism. Hitler saw Jewish people living lives of luxury while he lived a life of poverty.
Who or what was there to stop him?
To make no jews in the world, and hitler hated them because they were smart and brave, etc.
Hitler did not understand the Jews or know any Jews, so he was terrified of the Jews, which caused him to hate them and scapegoat them for all of the problems in the word.
Hitler did not really convert Germans to hate the Jews. Germany was already an anti-Semetic society when Hitler came to power and therefore, it was easy for Hitler to convince Germans to go along with his plans for Jews.
Hitler did not hate the Jews the most; a man called Julius Streicher hated them more, was even kicked out of the Nazi Party because he was too anti-Jewish.
The Jews were the target of Hitler's hate campaign.
