There are two major reasons:
1) Irrelevance: Hitler's hatred of Jews was racial, not religious. He classified a person as a Jew if at least one grandparent was a Jew at some point in time. As a result, it would not matter if a Jew left Judaism as concerns Hitler and the Nazis.
2) Personal Integrity: Jews, like people of any other religion, have pride in their origins, religion, and customs. Jews do not just leave Judaism because violence comes their way; they stand their ground as martyrs in defense of the faith in their God.
Sadly, the Jews.
Hitler's opinion of Jews had nothing to do with God, and the Holocaust had almost nothing to do with religion: the Nazis saw the Jews as Communists.
Genocide. However, what bothered the Nazis about the Jews were race, not religion.
Yes, it is estimated that Hitler killed about 6 million Jews.

If you're referring to World War II and Hitler's holocaust on the Jews... Hitler was against the Jews more as a race than as a religion. If a Jew practiced Christianity, it did not matter, they could still be taken to concentration camps, even if their families had converted generations ago. Also, if the people still practiced Judaism, they would rather face the wrath of Hitler than the wrath of God for changing religions.
He was Roman Catholic by upbringing - but why does the question assume that it was his religion and 'background' that 'made' him kill Jews? See related question.
Nazis hated the religion of Judaism.
There's no evidence that Hitler took any interest in Judaism (that is, the Jewish religion), but there is plenty of evidence that from about 1919 he was very preoccupied with Jews.
They practiced the religion of Judaism. They were raging jews and they praised Hitler because they weren't in touch with their feelings
To the best of my knowledge it was because Hitler imagined a perfect world everyone with the same religion, and everyone with blonde hair and blue eyes. The Jews were usually killed by being forced into the shower and whilst in there they were gassed and killed. The Jews religion got in the way of hitler's perfect world
Hitler became a hater to Jews because he thought it was not the right religion and his was Christan. ___ So you're trying to tell us it was all some version of 'Onward, Christian Soldiers' ... In fact it had nothing to do with religion, It was all about race and conspiracy theories.
