As to WWII: /wiki/Rescue_of_Jews_by_Poles_during_the_Holocaust
Polish Jews were the primary victims of the German Nazi-organized Holocaust. Throughout the German occupation of Poland, many Polish gentiles - at great risk to themselves and their families - rescued Jews from the Nazis. Evidence indicates there were more Polish rescuers than people from any other nation.[1]
As to Germans: /wiki/Occupation_of_Poland_(1939-1945)
Over 6 million Polish citizens - nearly 21.4% of the pre-war population of the Second Polish Republic - died between 1939 and 1945.[64] Over 90% of the death toll involved non-military losses, as most civilians were targets of various deliberate actions by the Germans and Soviets.[64]
Both occupiers wanted not only to gain Polish territory, but also to destroy Polish culture and the Polish nation as a whole
Losses by ethnic group were 3,100,000 Jews; 2,000,000 ethnic Poles
Nothing makes your responisiblity for ethnic Poles killed lower.
