@hvaces42 are you saying that Hatzolah responds on Shabbos to calls that are 100% definite Goyim? I think what you mean is that they don't ask questions, and cover every call indiscriminately.
There is no such thing as 100%. They dont answer the phone "Hatzolah, Are you Jewish?" They answer "Hatzolah, What's your emergency?" And even if we know its a goy we have to do it mishum eivah. Those are the halochos I learned.
I'd like to ask you then, do you not understand that the reason why Jews can't donate organs while they can accept isn't one of selfishness rather it's one that's based on the law of respecting our deceased? (Not asking you to agree, just if you can see the difference)
This all has nothing to do with respecting the deceased. Harvesting organs requires a live donor. You as a non-jew don't consider someone who is brain dead alive. Therefore, you harvest their organs and then pull the plug after the organs are removed. Us as Jews do not believe that a brain dead patient is dead therefore we have no means of harvesting live usable organs. As we do not pull the plug from living patients.
As far as using tissue and retinas from dead patients that's the only instance that I can think of when one would be taking something from a dead patient and as far as that's concerned we do not carve up the Dead. It's not respectful.
