Cons of Euthanasia

1. Euthanasia would not only be for people who are "terminally ill." Now they already extend euthanasia to those aren’t “terminally ill”. There are many definition for the word “terminal”. Some law define “terminal” condition as one from which death will occur in a “relatively short time”. Others state that death is expected within six months or less. However some euthanasia activists have dropped references to terminal illness, replacing them with such phrases as "hopelessly ill," "desperately ill," "incurably ill," "hopeless condition," and "meaningless life."

2. Euthanasia can become a means of health care cost containment.
"...drugs used in assisted suicide cost only about $40, but that it could take $40,000 to treat a patient properly so that they don't want the "choice" of assisted suicide..." ... Wesley J. Smith, senior fellow at the Discovery Institute.
Euthanasia could become a means of cost containment in such a climate which is emphasis on health care providers to contain cost. Legalized euthanasia raises the potential for a profoundly dangerous situation in which doctors could find themselves far better off financially if a seriously ill or disabled person "chooses" to die rather than receive long-term care. Savings to the government may become a consideration because this could let governments cut back on paying for treatment and care and replace them with the “treatment” of death.

3. Euthanasia is a rejection of the importance and value of human life.
With Euthanasia no one's life is being saved - life is only been taken. From the history, we already know the dangers of Euthanasia and that is the reason why only two countries made Euthanasia to be legal. Almost all societies, even non-religious ones have made Euthanasia as a crime.
