Self-Determination

How are we to make the moral move from my right of self-determination to some doctor’s right to kill from my right to his right?Where does the doctor’s moral warrant to kill come from?
Ought doctors to be able to kill anyone they want as long as permission is given by competent persons? Is our right to life just like a piece of property, to be given away or alienated if the price (happiness, relief of suffering) is right?
And then to be destroyed with our permission once alienated?

In answer to all those questions,will say this: Have yet to hear a plausible argument why it should be permissible for us to put this kind of power in the hands of another, whether a doctor or anyone else.

The idea that we can waive our right to life, and then give to another the power to take that life,requires a justification yet to be provided by anyone.
