That was the phrase going through my mind while watching this anime; all of them--victims of despair. Uneventful occurrences happened in their lives that eventually pushed them to do the things that they did. The anime didn't attempt to humanize them--instead, the anime tried to portray what events can influence a person enough to think that murder is a justifiable thing to do because everyone should be as miserable as they are. That was the connection shared between those two episodes; the madness that resides within resurfaces just because of a certain chain of events. I don't empathize with the killers, of course. What they did was truly unforgivable--but with what they went through, one can't help but wonder if they were as much of a victim as everyone else.
In terms of the plot, I honestly found it great. There were no plot holes and everything was explained properly, down to the trauma the killers experienced that led them to become who they are. Everything was concise and I see not loose ends for both of the episodes. While it might seem rushed, I think the decision of the anime to show the peak events of their lives (that connects on why they became a murderer) was enough to speak for the plots of the episodes themselves.
In terms of characters, I think they were decent. Inserting a chuunibyou out of nowhere was kind of confusing for me, especially for an anime that endorses itself as a psychological thriller anime. But, it wasn't really enough to distract you from the main plot of the story either which is why I think it was okay.
All in all, I think it's worth watching. You can finish this anime in less than 2 hours (which is good) and the ending of the episodes were satisfactory enough to leave you with no questions asked.
