The character Cioccolata has a reputation for torturing his victims, along with his partner Secco who records videos of the victims’ faces. The two are vaguely shown brutally torturing a gay couple early in part 5, and other grotesque examples of what Cioccolata does are listed. Also in part 5 is “the torture dance”, wherein main characters dance while another character’s retina is burned as his disembodied head is dangling from a fishing line by the eyelid. Despite how gross that sounds, it’s mainly played for comedy.

An orangutan watching a girl in the shower, Joseph spying on Lisa Lisa while she's taking a bath, Hayato spying on Kira and even taking pictures, the list goes on.
Although there is no explicit antisemitism, the nazis in Part 2 are handled very poorly which viewers should be aware of. The anime adaptation doesn't include swastikas/iron crosses and refers to them as "German Soldiers", however the character Stroheim still regularly throws up the nazi salute. He also receives a touching sendoff, gets more screentime and fight scenes than some main characters do, and is well loved by the fanbase. The villains regularly murder nazis which is very sexy of them though.

In part 6 there is a naked man’s butt shown as he showers, and the main character strips to be searched before going into prison (though only the top of her breasts and part of her butt are shown). Many characters dress somewhat immodestly but its not too bad.
in the animated parts, there are no real sex scenes. in the not yet animated ones (7 and 8) there are a couple implied sex scenes but no one explicitly loses their v-card.
an old character in part 4 is referred to as senile several times, as he has trouble hearing and sometimes gets confused/misinterprets instructions. however, it is minor and he does not have a diagnosis.
