Euthanasia is unethical

Ok so here's the gig, I have three logical moral arguments against euthanasia. This is my first time debating this subject while I know my opponent has ample knowledge of experience with it so bear with me here.The contentions are as follows:1. It denies the value of human life.2. It plays God.3. It is a slippery slope.My arguments will be much more based on philosophy and logic than numbers and figures.1. It denies the value of human lifeThe original Hippocratic Oath states in paragraph for that "I will not give a lethal drug to anyone if I am asked, nor will I advise such a plan;" (1) That directly speaks to euthanasia. The rest of the text makes this truth very obvious for any physician "First, do no harm." In light of that, euthanasia undermines the value of human life, no matter the condition. This will be discussed more in argument three, which is the meat of my argument. I understand that their is much pain in the world through disease, my grandfather had a heart attack and his health in dwindling into dementia and a life of pain for which there is no remedy. There have been days I have not even been able to see him because he can't get out of bed, and others where I cannot give him a hug because he is in so much pain. However, he has made one thing clear: He values human life.He values it to the point that he sat me down and said no matter how much it hurts, a person should fight through the pain to make the most of life, because you only get one shot.This is the fundamental truth of the matter: human life is the most valuable thing we have. We should never waste any of it.2. It plays GodComing from a person who has struggled with suicidal thoughts over the years, I found new life in Jesus. So I need to include this argument even if it is moot if my opponent is non-religious. If my opponent is religious, this needs to be answered.George Whitefield has been famously paraphrased to say "We are immortal until God is done with us." I completely agree. We did not give ourselves our own human life. We do not own it. We had no right to say when, why, and how we were born into this world and we have no right to say when we can leave it.Day someone gave a valuable gift, a Mustang GT. You drove it everywhere. It was the best thing ever. Sure it took some upkeep and gas, but it was nice. Then you crash into a telephone pole. Who tells you whether that car is totalled? You or the mechanic? If the mechanic says "even with it messed up you can still drive it. It's just not as nice." would you just blow out the engine? No, you'd work with it. It's still valuable and it still has worth, even if it's not as nice.It is not a person's choice whether their life is over. A person should not commit suicide and play God like that. If your mind is active enough to make a decision like that, your life is still worth a lot.3. Slippery SlopeIn the early 1900's, acceptance of physician-assisted suicide was growing, but then something unexpected happened: The T4 Program. It was the Nazi forced euthanasia program. It started with severely retarded and handicapped children... then it was adults... then bombing victims... but by the end, foreign workers they did not need were being killed. This was a separate program from the Holocaust. (2) Do you think this started on it's own? No, it started when people began to think life was not as valuable as once thought. It started when people started playing God. It started with physician assisted suicide. Once that first barrier that "Life is too valuable" was broken, it became a free-for-all. I once debate a girl on this site who actually said that she thought it was not just not immoral, but actually ethical to kill every child with Down Syndrome. I do not believe it to be ethical or right to delve into a grey area that also gets bigger. Where children are now being aborted, just because they are handicapped. Where children are shot in their schools by their own classmates. Euthanasia is just part of a larger battle for the value of life. Thank you and goodnight. Sources: (1) https://www.nlm.nih.gov...

I always appreciate life when I watch it. This is not part of my contentions only to further implicate my points. http://www.youtube.com...
