In 40-some-odd years of Trek, I have never seen anything to suggest that Spock would let the inhabitants of Vulcan die at the hands of a psychotic time-traveler and not try to undo that tragedy.
Undo it? How?
You make it sound like he's some sort of wizard who can undo anything that happened. If he is, why didn't he, in some 40-some-odd years of Trek, undo the destruction of numerous other planets - say, those destroyed in the Doomsday Machine
Imagine what a fun show would that be, Spock constantly undoing anything bad that happened to anyone...
