He was an animal, yes, and according to your definition he must have commited genocide because he killed based on the ethnic group his victims came from
Its not my definition you twat also genocide is a planned extermination with the aim of eliminating a certain group, Morel killed Silesians, Poles and Germans especially since Silesians fell into one of the two categories ethnically.
So, not an "odd German", but mostly German. And not "primarily Polish civilians",
Sorry bud but Silesians were Polish, according to Russians and their local puppets they were not.
So why do you call it murder then?
Because it was not aimed at elimination of any particular group thats for one, and because he worked without consent of the goverment which means the part about "organized" is also false.
Only because Morel was Polish?
Morel was a Polish citizen but for all intents and purposes he was a Jew and didnt identify himself with Poland, he participated in murder of Polish civilians based on their nationality so calling him Polish is a bit of a stretch, a Polish citizen ceirtanly but beyond that he was a Jew.
Inmates maltreated and tortured on purpose until the were dead.
Again you mix mistreatment and murder with delibarete methodical elimination of an entire group, there were no standing orders to Morel (as far as we know) to do this to people, it was tolerated but not encouraged and it didnt lead to or was not aimed as total or partial elimination of any ethnic or political group and that intent makes all the diferrence in most definitions.
For all i care you can call it how you like it, genocide and mass murder are equally bad in my eyes but as far as legal definitions Morel was not guilty of genocide "just" mass murder.
