Like, frankly, any passengers that are aggressive towards the train crew might as well be told to walk back to the nearest bus stop. Like seriously, in this case especially (a high speed train) the utmost focus should be given to safety, so anyone going against that (like putting pressure on the train crew) should be ignored if not fined/booted of the train.

Also in this case - why the hell they just did not wait for the primary safety system to go back online before doing anything ? Is it so faulty that they get used to it being broken or what ?

And baring that, how is the train even able to go full speed without the primary safety system being operational ? It really should be hardwired to cap the speed at 40 km/h or even less (including zero) unless the safety system is confirmed online and operational.

IIRC the japanese Shinkansen trains use a system called ATC (https://en.wikipedia.org/wiki/Automatic_train_control#Japan) since 1964 (!) which automatically starts breaking if a train goes faster than the maximum allowed speed in a track circuit. So presumably if connecting with the track circuit is lost the maximum speed defaults to 0 & all trains stop until proper protection is restored.
