In E2, the participants discuss a black and white puppy that was stabbed after the person. There isn't ongoing video footage, but you do hear a little whimper. At around 19:50, a still photo of the deceased puppy is shown.
In the 2nd and 3rd episode they go into detail about how Luka Magontta (the killer) manipulated law enforcement and his mother into thinking he was being abused and forced by someone else to kill
Two kittens are killed by being vaccum sealed in a bag. The beginning is shown, and the cats dying is heard but not seen, and described in detail. Video footage of the dead kittens is shown. A cat is also drowned in a bathtub. Again, the cat is now shown being killed, but there is a shot of it taped to a broom.
The whole series is about someone on the internet harming and killing animals, so there are many dead animals shown. It’s not particularly graphic, in my memory, but certainly upsetting
The videos don't show the actual deaths, but it's clear what's about to happen which can be troubling for some people. These are the parts in each episode I would recommend skipping (I managed to get through by muting these sections and only watching the bottom part of the screen with subtitles to know when it was safe to look). The parts between asterisks are the most intense.

After murdering Lin Jun, Luke dismembered & decapitated his body, mailing the parts across Montreal. None of this is seen visually other than snippets of the actual murder video (prior to any bloodshedding) & evidence photos of the body parts still wrapped up, but it is spoken about at length.
Murders of kittens and a human are described in heavy detail and some audio clips are put on but are not really of the actual murders, just clips of right before.
Jamsey, the internet troll who used Luka Magnotta's photo as profile pic on Facebook and who knew Luka was the one the FB group was looking for, killed himself after the group cyberbullied him, convinced that he was the killer. Jamsey was already suffering from depression and the bullying pushed him over the edge.
as with a lot of true crime, unnecessary use of Cluster B terms such as "narcissistic", and "psychopath". This is usually done with intent on being derogatory or insulting, regardless of wether the killer actually has NPD/ASPD or not.
there isn't but there is a lot of insinuations that participation in BDSM and kink is somehow a slippery slope to becoming a serial killer, so no BDSM content or implications but there is a lot of kinkphobia and a lot of wild assumptions from kinkphobic people about the scene that are laughably innacurate but could be triggering for some within the scene given that for some reason people actually believe some of this kinkphobic stuff
The whole documentary is very upsetting including the ending, would not recommend to people sensitive to murder of humans or animals, torture and disturbing situations.
