Euthanasia How far is too far?!

I was recently reading about euthanasia and its horrible that this medical procedure has the option to take away lives for those that desire it. Its like having the right to commit suicide and kill those that are in pain. The pros about this "peaceful killer" is that it is a way to relieves extreme pain, the relief of the person's quality is low, frees up medical funds to help other people and it is another case of freedom of choice. The cons are that euthanasia devalues human life, health care cost containment, physicians and other medical doctors should not have the right to cause death to other people. and not only is euthanasia legalized for the terminally ill but also for others who desire death.
I think that euthanasia should be only be for those people that are very ill and have no chance of ever getting better and ending their misery. But i also believe that no one deserves to die because there has been cases of surprising recoveries. I think the only person in charge of taking away life is God and no one else.
What do you girls think about Euthanasia? Is there any other findings about this medical procedure that you want to share? I only know that basics so knowing more about this will really help thanks.
