Hitler did not want to kill the Jews
There's no shortage of blood-curdling imprecations, threats and promises of Hitler in regard to the destruction of the Jews. Here are four statements from 1939-1942:
(a) January 21 1939
Adolf Hitler told the Czechoslovakian Foreign Minister, Dr. Frantisek Chvalkovsky, that: "Our Jews will be destroyed." (Hoehne 400)
(b) January 30 1939
In a major speech to the Reichstag, Adolf Hitler predicted the destruction of the European Jews in the event of a world war:
"Europe cannot find peace until the Jewish question has been solved. It may well be that sooner or later an agreement may be reached in Europe itself between nations who otherwise would not find it so easy to arrive at an understanding. There still exists sufficient available land on this globe . . . .
One thing I should like to say on this day which may be memorable for others as well as for us Germans. In the course of my life I have very often been a prophet, and have usually been ridiculed for it. During the time of my struggle for power it was in the first instance only the Jewish race that received my prophecies with laughter when I said that I would one day take over the leadership of the State, and with it that of the whole nation, and that I would then among other things settle the Jewish problem. Their laughter was uproarious, but I think that for some time now they have been laughing on the other side of their face. Today I will once more be a prophet: if the international Jewish financiers in and outside Europe should succeed in plunging the nations once more into a world war, then the result will not be the Bolshevizing of the earth, and thus the victory of Jewry, but the annihilation of the Jewish race in Europe!" (Nazism 2, #770)
(c) November 5, 1941
In an evening conversation with his intimates and staff, Adolf Hitler said: "The end of the war will see the final ruin of the Jew. And their egotism goes so far that they're not even capable of risking their lives for the defense of their most vital interests." (Hitler's Secret Conversations 135)
(d) January 30 1942
In a speech at the Berlin Sports Palace, Adolf Hitler again predicted that the European war would end with the destruction of the Jews:
. . . [T]he war will not end as the Jews imagine it will, namely with the uprooting of the Aryans, but the result of this war will be the complete annihilation of the Jews.
Now for the first time they will not bleed other people to death, but for the first time the old Jewish law of an eye for an eye, a tooth for a tooth, will be applied.
And -- world Jewry may as well know this -- the further these battles [of the war] spread, the more anti-Semitism will spread. It will find nourishment in every prison camp and in every family when it discovers the ultimate reason for the sacrifices it has to make. And the hour will come when the most evil universal enemy of all time will be finished, as least for a thousand years. (Gilbert Holo 285)
(2) As for whether Hitler was aware of the mass murders of Jewish civilians, we have:

In the years prior to 1942 (Stalingrad) no Jews died in concentration camps
In the first place, this statement is false. Jews had been dying in concentration camps since 1933. In the second place, it doesn't prove the premise that the final solution was undertaken only after Stalingrad.
Here are some German documents or links to sources on the mass killings of Jews in Poland 1939-1942:
