Of course if Morel hadn't been Jewish, he would most certainly have been nailed to the wall as a warning to others. Just look at what happened to another of the commanders of a Polish concentration camp, Czesław Gęborski.
In October 1945 he was dismissed from the post [of commander] and charged with setting fire to one of the barracks in the camp and ordering gunfire on the inmates trying to put out the flames, an incident in which 48 prisoners lost their lives.
Bet he got a long sentence, eh?
No. He got promoted.
However, by 1947 the investigation against him was dropped without any charges being presented and Gęborski was promoted to the rank of captain.
But he must have been done after Stalinism ended, right?
Nope
In 1956, during the Khrushchev Thaw following the end of Stalinism in Poland, the investigation was resumed and Gęborski was arrested, but the court declared him not guilty. Gęborski then continued his career in the ranks of the Służba Bezpieczeństwa. In the 1960s he demanded compensation for the 22 months spent in prison prior to his trial, but the court declared that the arrest had been necessary.
But this was communist Poland. When Poland became free surely he answered for his crimes!
Finally, after the end of communist rule in Poland, in the late 1990s, the trial for the 1945 incident in £ambinowice was resumed by the local court in Opole. However, it had to be postponed - and finally terminated in 2005 - due to the poor health of both Gęborski and the witnesses. Gęborski died June 14, 2006.

https://en.wikipedia.org/wiki/Czes%C5%82aw_G%C4%99borskiMorel's co-commander at the Zgoda Polish concentration , a certain Aleksy Krut, was not Jewish and by some amazing oversight was never brought to trial either.
As for Wolinska, being a Jew was the only reason she wasn't prosecuted. Look at what happened to the judge in the Fieldorf case, Maria Gurowska. She was banged up for life wasn't she? Nope, although a case was opened against her in 1992 (a mere three years after Poland became free), she just didn't bother turning up to any of the proceedings and happily lived out the remaining six years of her life.
That Wojciech Jaruzelski, he's a Jew too. Which explains why he's never been brought to trial.
