I have a theory that Euthanasia would cure BPD as the BPD thrives off of baiting suicide constantly but in a society wehre suicide is normalized, this would not even be possible.
LIKE a bpd wakes up, threatens to an-hero. Sometimes multiple times in the single course of a day. Obviously this is a concerning issue to bystanders. Suicide is seen as an act of treason, and conjures guilt and protective signals in those around them. Sometimes it seems as though the goal of the bpd is to push limits as much as possible. This is a beautiful thing. BPD's are gods most blessed and cursed creatures. However, if euthanasia was voluntary and accepted, what outlet would the bpd turn to for excess? Perhaps bpd is even caused by the state's control over the death = shame apparatus. Replace the phone booths and the outhouses with euthanasia booths on the street corners, they wouldnt even have to invent anti-homeless hostile architecture then.
