I fail to understand why German high command, particularly the SS continued to attempt to solve the 'Jewish question' even after their primary plans for relocation and deportation we no longer feasible, especially by the summer of 1941 a swift German victory (which the plans of the time to solve the Jewish question relied on) no longer appeared to be realistic. Why not abandon this issue until a later date in which they can formally focus on it. Goring was even opposed to the distraction this posed on the German war effort. I understand that this is a tough question to answer and is highly unlikely to be definitively answered, but anything to help me wrap my head around it would be appreciated.
The first thing you have to do is understand the the goal to be Judenrein, clean of Jews, was a central part of Nazi policy. Racial purity was a central concern of the Party, and to be part of it was to believe in working towards the goal of a Germany cleansed of Jews, at least, on paper. It was also to believe in the superiority of the Aryan race, the need for greater lebensraum (living space for Germans and ethnic Germans), the inferiority of Poles, Slavs, Romani, anyone visually not white, the disabled, etc. Hannah Arendt's Eichmann in Jerusalem: A Report on the Banality of Evil might help you understand the mentality.
Beginning in 1933, Nazi policy towards the Jews was to make life as unpleasant as possible so that they would leave. Their anti-Jewish laws were passed under the assumption that the Jews would have someplace to go, or, in other terms, that the international landscape was one open to accepting Jewish refugees. This was not the case. And as Germany made life increasingly unpleasant for the Jews over the course of the 1930s, the Nazis grew frustrated by the relatively small number of Jews who were leaving. Now, there are complex reasons behind this, some having more to do with gender than with anti-Semitic immigration policies, but the crux of the matter is, that, by 1938, not nearly enough Jews were out of the Third Reich. Kristallnacht succeeded in pushing more of them out, but the fact remained that there were extremely few places willing to receive them (I can dig up some stats on this if you'd like). The goal to make the Third Reich Judenrein by way of making life so unpleasant that the Jews would be forced to leave didn't work because there was nowhere for them to go.
The Nazis considered mass deportation as a Final Solution. Madgascar was considered as a potential place where they could move the Third Reich's Jewish population. Siberia was also considered, I believe.
In the first six weeks of Operation Barbarossa, the Nazi Invasion of the USSR beginning in June 22, 1941, German troops would commit mass murders of any Jewish community they came across while making their way through the Western Soviet Union. This, combined with the failure of the Final Solution by way of forced immigration, and by way of forced relocation to territories not yes conquered, led to Hitler's decision to deport the Third Reich's Jews to the occupied East, and achieve the Final Solution by way of mass extermination. This iteration of the Final Solution was put into place on October 15, 1941.
This answer condenses a lot of highly complex issues, so please don't be shy with follow-ups!
