Just to correct a comment by nisht…..(cant spell his name): There IS a MAJOR diffence about the length of life left as far as “retzicha’ goes. If one kills a ‘treifa” one will not be convicted of “retzicha”. And someone who is clinically dead is certainly a ‘treifa” that will not live a year. This is not to say that one can hasten death ,clearly, you are not allowed to do that. However, you cannot equate “jaharog ve’al jeavior’ to the last minutes of a living person.
