I voted yes because in this episode the perpetrator keeps someone's cats. They fail to give these cats medicine, end up taking them to a kill shelter and one has to be euthanised because they become too sick. They kept another two cats and it's unclear what happened to at least one of them. Another cat dies, supposedly from natural causes, but it's implied they could actually have been killed. Nothing is shown on screen but I was a bit taken aback by it, as I wasn't expecting it.
The perpetrator commits suicide while in jail after commiting murder. The way they commit suicide is mentioned, but not many details are given. The commentary from the people in this episode is not the most empathetic, although, within the context of said episode, it's understandable (not just because of the murder, but because of other stuff too).
Not between spouses or parents/children, but between roomates, which leads to a few instances of domestic abuse being filed by some of them, since they do live in the same house.
Voting yes because a lot of the cases in these episodes might end up with the resolution of the situation, but the aftermath isn't always the best (people develop resentment, PTSD, etc.)
Parents send their son to a mental institution. The treatments of the period (70s-80s) weren't good and mental health was severy mishandled, so this can be triggering for a few people, even though it's not explored in detail. I got the impression parents only sent their son there because the information at the time was limited, but since it's not clear it can be seen both ways.
In this episode there are a few instances where blood/gore is shown, although the entire show uses mostly cartoon for the reconstruction of the scenes. Some images of certain injuries are shown briefly throughout the entire season (cuts, swollen eyes, etc).
There is, however, a person with mental health issues (I believe it was shcizophrenia) who is taken advantage of. It's not described or shown in detail, but it's clear it's one of the elements that made them a target for the perpetrator.
