If you think for a moment that if they would've done differently they would've survived, you are sorely mistaken. We don't know why God does what He does, but we can be sure that if He decides something it will happen.
That's the beauty of your religion. It's obviously a question of what is the necessary hishtadlus. I would suggest anyone considering it should ask their Rabbi.
Yup. It is a beautiful thing. We get to use hishtadlus and religion as a means of menuchas hadaas. At the end of the day god runs the world.
Gosh. Can we not learn lessons about hishtadlus from past events because that's the way it was supposed to be?
I wonder why additional precautions and safety measures were taken at Lag baomer the last few years. That was obviously something that hashem wanted at that time. Why change going forward though??
