DaasYochid; We must be learning different seforim. “lebidik yankel” writes: (I quote): “someone who stops learning because of pikuach nefesh that was not efshar laasos al jedei acherim is doing what the haloch requires. It would have been far better for him to have continued learning”.
“memechilas kevod toroscho: the Taz does NOT say that. On the contrary, he writes (I quote) :” ein dovor ho-omed bifnei pikuach nefesh” He dismisses the derisha who says that talmud torah is before pikuach nefesh (!) and does not bring down the Perisha that does say what you said. From the mishmo-os of the taz is clear that pikuach nefesh is above all. HE DOES SAY that the “sechar” (reward) for talmud torah can be greater than pikuahc nefesh, quoting the gemoro end of Taanis.In actuality, however, you must save souls first.
