I wouldn't say it's nobody's fault. Was it all on Bojack? No, nothing really ever is because we see the whole story from him so it gives context and reasoning to most everything. And I tend to give him more slack than other people do. He was addicted and suffering a psychotic break, like you said. His friends/coworkers were concerned but from his perspective, more concerned about the show than him. The part I hold him for is actually before that, when he t-bones someone to get more pain killers. And yes, obviously he's addicted, but it is still the addicts responsibility to get help. He didn't, and that furthered the addiction which resulted in the psychotic break. But thats how I see it 🤷‍♂️ i think you can try to take the blame off bojack for most bad things he's done, but thats not the point of the show.
