I don't really know much about the subject but i do know that the Lodz gheto wad controlled by a strong jewish council(its called judenrat un german) and its leader was basically a fascist dictator. That man,haim rumkowskey,is one if the most controversial figures in the holocaust. So i think a better question would was it hard for the judenrat to make the decisions thar it did?because the jewish police was just executing their orders. As said i dont know much but i recommend you to read about the judenrat and if you are looking for personal opinions from survivors check yad vashem's site.
