There are a few scenes where male Jews are being executed. They are naked, and are mostly seen unrestricted from behind, so their buttocks are on view. All front views are restricted, with the men using their hands to cover their genitals. After the executions we are shown the bloodied bodies, but again they have been carefully arranged so that the men's genitals are not visible. In a later scene, female Jews are being taken to be put to death in a gas chamber. They undress before being taken into the chamber, and most women use their hands to cover their breasts and pubic area. However, one or two do show their breasts and/or pubic hair briefly. None of the nudity can be classed as sexual. Sex talk includes a Nazi official violently interrogating a Jewish prisoner about who his "whore mother and the pimp who raped her"....

Much, including many shootings, wartime battles, burnings of Jewish businesses (Crystal Night in 1938) and synagogues, whippings, beatings and kickings.

Some. Go. Damn, Jesus, G/D

Some of both, e.g. at parties.

The entire miniseries has many such scenes from the above mentioned Violence & Gore.
