Jack Kevorkian — American Activist born on May 28, 1928,

Jack Kevorkian, was an American pathologist, euthanasia activist, painter, author, composer, and instrumentalist. He is best known for publicly championing a terminal patient's right to die via physician-assisted suicide; he claimed to have assisted at least 130 patients to that end. He was often portrayed in the media as "Dr. Death"; however, many consider him a hero as he helped set the platform for reform. He famously said, "Dying is not a crime.".. (wikipedia)

Anytime you interfere with a natural process, you're playing God. God determines what happens naturally. That means when a person's ill, he shouldn't go to a doctor because he's asking for interference with God's will. But of course, patients can't think that way.
The patient's autonomy always, always should be respected, even if it is absolutely contrary - the decision is contrary to best medical advice and what the physician wants.
My intent was to carry out my duty as a doctor, to end their suffering. Unfortunately, that entailed, in their cases, ending of the life.
I will admit, like Socrates and Aristotle and Plato and some other philosophers, that there are instances where the death penalty would seem appropriate.
Five to six thousand people die every year waiting for organs, but nobody cares.
