I mean there a countries where a person can die by volition for example in switzerland, so if you have a disease and suffer a lot you can let yourself be euthanised. Things get messy because even the option can make it so people could gaslight each other into getting euthanized to get inheritance quicker and all sort of that nasty shit. And I guess animals can’t really spell out if they want to die or not.
When it comes to deciding for people who can’t decide for themselves, in germany you can allow somebody else before you fall in coma to decide about stuff for you regarding health so they can ask the doctors to turn the machine of keeping you alive.
I guess its also a strict taboo for doctors with the vow to protect lives. But there’s been a push for it in some parts of the world. There are also stings in history where people with mental illness were regarded as “not worthy of living” in nazi germany for example and basically killed. So thats one reason for example it also remains a taboo with many liberal countries rethinking on the (consentual) euthanasia for those suffering and having the legit wish to die.
In Germany where I’m from you’re legally allowed to be prescribed medication that ends your life but you have to administer it to yourself. There also the difference of passive and active euthanasia. Active is where doctors can administer it to you with consent. Passive is what I described for Germany. It should really be allowed more commonly in the world tho. The passive one sucks for people who are paralyzed and can’t administer it to themselves because anyone else that does it will only do so illegally
