The tradition held, and holds, that danger to life overrides the Sabbath: “uncertainty concerning a life-threatening situation overrides Shabbat” (Mishnah Yoma 8:6, the principle called pikuach nefesh, “saving a life”). The watchers in the synagogue are not monsters; they stand on a real distinction. A withered hand is chronic, not mortal: on their categories it can wait until sundown. Jesus refuses the wait: “Is it lawful to do good on the sabbath days, or to do evil? to save life, or to kill?”

Notice the halakhic edge the scene itself sharpens: Jesus heals by a word. He performs no act that any category of forbidden labor can name; no kneading, no carrying, no burden. His accusers watch a man stretch out his own hand and are left with nothing to charge but the goodness of the deed and the authority of the doer. That the Pharisees then take counsel “with the Herodians,” the party of Herod Antipas they otherwise had little in common with, shows how far the offense reached beyond law.
