Why does oskar schindler come to poland? does that make him any better than the conquering germans?

Following the German invasion and occupation of Poland, Schindler moved to Krakow from Svitavy. Taking advantage of the German occupation program to “Aryanize” and “Germanize” Jewish-owned and Polish-owned businesses in the so-called General Government (Generalgouvernement), he bought Rekord Ltd., a Jewish-owned enamelware manufacturer and converted its plant to establish the Deutsche Emalwarenfabrik Oskar Schindler (German Enamelware Factory Oskar Schindler), also known as Emalia, in November 1939. While Schindler operated two other factories in Krakow, only at Emalia did he employ Jewish workers who resided in the nearby Krakow ghetto. At its peak strength in 1944, Emalia employed 1,700 workers; at least 1,000 were Jewish forced laborers, whom the Germans had relocated from the Krakow ghetto after its liquidation in March 1943 to the forced labor camp and later concentration camp Krakau-Plaszow.
