Do you disagree with a terminally ill person making his or her own end-of-life decisions? Would you rather Big Brother intervene, regardless of the will of the patient or the closest family member?
The keyword there is "terminally ill". All of us are terminally ill - just which illness gets us.
And, some of us are not even dying until the "state" makes the decision it is time for us to go.
If the insurance companies are involved with promoting euthanasia, there will be many that will seek other insurance companies. If the hospitals kill the elderly when they innocently enter the doors of the hospital for help, the elderly will not go to doctors because of fear.
You say people should plan their end of life wishes. But, after a case like Terri Schiavo where the family wishes were ignored and she was killed, the elderly, the deformed, the bedridden will now die without the feeling of loving relatives surrounding them, but the fear that those standing around them are really killing them.
Why would any wish such on any of those that brought us into the world.
