Interesting how ending someone’s life for medical reasons is viewed so differently depending on if they are human or non-human.
When they’re human, it’s “assisted suicide” and legal in only a handful of places (unless it is involuntary, which isn’t legal anywhere). Even when the one dying has made the choice to die, it’s taboo. Sometimes people say things like, “You’re playing God. Maybe they should pray more, then let God decide when it’s their time to die.”
When they’re non-human, it’s “putting them to sleep” and it’s legal everywhere. The one dying has no choice in it. It is seen as compassionate to end their suffering, and the humans involved are not viewed negatively or ridiculed, but comforted in their grieving or, for the vets, it’s just part of their job.
Sometimes the decision for death is partly informed by how much money proper care would cost. Sometimes that is the main reason for euthanizing an animal. Imagine if we decided whether or not a human should live based on how much it would cost to treat them and keep them alive.
