Question

Why did hitler and the nazi party hate the jews to the point of planning to exterminate the entire jewish race?

Answer 1

Although up till date, no concrete evidence of Hitler's order to exterminate was found, it can be said of his intents in his widely published book, Mein Kampf.

Antisemitism arose due to the positions of the Jews in societies, and more so aggravated following the 1929 Great Depression. As such, the Nazis promised a state where there was German purity (Aryan race) and sought to eliminate other races as part of their master-race ideology. Other than Jews who were eliminated out of this nationalistic clause, other "sub races" deemed unfit for the Nazi Party included the gypies and slavs, who suffered greatly under Nazi authority during WW2.
