The Nazis killed and slaughtered about 6 million Jews.
Poorly, 98% of sick and elderly Jews were killed.
Hitler treated German Jews as badly as foreign ones. He was murderous.
Generally it was the way that the Nazis (and the Germans) treated the Jews and arguably treated the Gypsies even worse.
very badly, only slightly better than Jews were treated
they starved them, stripped them, and treated them like dogs.
No, Jews were killed by the Nazis on 'racial' grounds. Converts from Judaism to Christianity and atheists of Jewish origin were treated in the same way as practising Jews.
Money made no difference. You couldn't buy yourself out of the Holocaust. The Nazis wanted to kill all Jews that they had control over.
The Nazis believed that the Jews were subhumans and did not deserve to be treated like people. So, the Nazis deported the Jews and isolated them into ghettos (the Warsaw Ghetto was the largest) in order to perfect the German race. Hitler believed that Jews living with Aryans (pure Germans) would ruin his master race, and therefore, he came up with his 3 solutions.
Nazis arrived after Jews.
Nazis transported the Jews by train mostly.
Nazis and Jews are not alike in any way. Those people who say or believe that Nazis and Jews are alike are not only wrong, they are intolerant and bigoted. Nazis, the followers of Adolph Hitler, discriminated against Jews, and murdered or tortured many Jews in the Holocaust. Ask any Holocaust survivor, and they will tell you how the Nazis harmed the Jews. They will also tell you that Jews are not Nazis, and are not like the Nazis in any way.
Elderly Jews were gassed on arrival at death camps, as they were no use to the Nazis for heavy manual work.
