How would we be affected and remember Hitler if he did not include genocide in his agenda?

we would still think of him as an evil, deranged man, as his ambition to conquer Europe and the way he led Germany in the war was criminal even when Nazi policies towards minorities and scapegoats are ignored. The Allies would still have battled to destroy Nazism - remember that in 1939 when the war began the UK and France committed themselves to fight Hitler because of his expansionist policies, not because of the Nazis' policies towards "inferior races". Although the Allies knew that Hitler was carrying out atrocities during the war, it was only afterwards that the full scale of the Nazis' genocide was revealed.

HITLER DID NOT ATTACK JEWS. it was Hitler himself who favored creation of Israel and immigration of Jews to Palestine and also offered them free transportation. However Rabbi Abba Hillal Silver of Cleveland and Rabbi Stephen wise of New York assailed the decision on the ground that it will make Jews a pauperized salesmen of German made goods (see New York Times Dt January 15, 1939).

there was no holocaust.

We'd still remember him as the person who wanted to conquer Europe, and as the person defeated by the Allies. We just wouldn't think of him as a wholly evil person, but a slightly less evil person.
