I would think d’rabbonon, but regardless, his foolishness shouldn’t change the fact that it’s pikuach nefesh.
It certainly does. The guy who is subject to pikuach nefesh isn’t allowed to decide that he doesn’t want to do any issurim so someone else should do issurim instead.
I’d assume you’re joking. But there are cases that you’d be right. If the pt. wasn’t in danger until it was too late. Btw, I’ve put in lines for pts. on Erev Yom Kippur.
I’m not joking at all.
