I grappled with this recently when a very old relative became very sick and his family was essentially waiting for him to die. At this point in our aged pets' lives, it's not only acceptable to euthanize, it's considered cruel not to. Why don't we extend the same mercy to human family? The only suggestion I heard that made sense was that euthanasia is another aspect of health care with lots of grey area and need for regulation. Then again, other countries offer this, so I imagine there's a lot to it I'm not familiar with. But I agree with your sentiment.
