For C.F.
The Talmudic and scriptural support for what I am saying:
Probably the earliest story regardomg euthanasia is found in the Talmud (Avoda Zara 18). One of the ten martyrs, Rabbi Hanina ben Teradyon, was burnt at the stake holding a Torah scroll. His students stood around and said to him, “Rebbe, open your mouth. Let the flames and smoke enter your body and choke you so that you will die quicker and not suffer this terrible torture.”
He said, “No. G-d gave me my soul. Only He should retrieve it from me.”
The Talmud states as follows: "One who is in a dying condition (goses) is regarded as a living person in all respects (didn't find source yet)." This rule is reiterated by the codifiers of Jewish law including, Maimonides and Karo. The Talmud continues:
"One may not bind his jaws, nor stop up his openings, nor place a metallic vessel or any cooling object on his navel until such time that he dies, as it is written: Before the silver cord is snapped asunder (Ecclesiastes 12:6). One may not move him, nor may one place him on sand or on salt until he dies. One may not close the eyes of the dying person. He who touches them or moves them is shedding blood because Rabbi Meir used to say: This can be compared to a flickering flame. As soon as a person touches it, it becomes extinguished. So too, whosoever closes the eyes of the dying is considered to have taken his soul (didn't find source yet...)."
Other laws pertaining to a goses, or dying person, such as the preparation of a coffin, inheritance, marriage, and so forth, are then cited.
The Talmud also mentions: "He who closes the eyes of a dying person while the soul is departing is a murderer [lit. he sheds blood]. This may be compared to a lamp that is going out. If a man places his finger upon it, it is immediately extinguished (Shabbat 151b)." Rashi explains that this small effort of closing the eyes may slightly hasten death.
“Against your will you were born, against your will you die, and against your will you are destined to give an account before the supreme King of kings, the Holy One, blessed be He” (Ethics of our Fathers 4:22).
