RE -“health, in SA by shabbos and yom kippur it says we rely on doctors. If we cannot trust doctors, whom do we trust?”
Why don’t you tell the Truth?
We trust them to Be Machmir on Pikuach Nefesh.
So we trust them to desecrate the Shabbos & eat on YK.
Like the Story with the Briskers.
But you want to say we can Trust them Nowadays to kill?!?
I never heard such a Krumme Sevorah!
If a Rabbi wants to apply the Tzitz Eliezer’s Heter nowadays, he’s got to check up on the Doc – if he’s Reliable!
