Let us be clear though that kapos who did their Nazi masters' bidding were doing same in order to survive
That's a really lame excuse. Pathetic really. A total revisionist lie.
Jewish Kapos and Judenraete could and should have defied the Nazis and sacrificed their own lives for Poland. But they decided not to by choice. They were Zionist Jews first and foremost and did not regard themselves as Poles anyway.
This is why collaboration came easy to them.
Their own survival meant personal and financial gain even if it meant Poland would be no more. But this was merely icing on the cake they were willing to bake with the Nazis.
What they did should be called betrayal but they never had any attachment to Poland.
They only feared being held to account for their actions and not for what their actions caused.
This is why so many of them easily abandoned Poland without a second thought after the war.
In their Zionist heads, Israel was always their homeland anyway.
