Sure, blowing something up can be a great teacher. At two previous jobs, I crashed prod on my first day there (and then fixed that bug, and made the sites much more resilient by the time I left). But lol, it would've also been fine if someone just told me "hey hold on, that might crash prod, let's double-check something first". Most people should respond well enough to gentle guidance genuinely delivered in the spirit of collaboration. It shouldn't take a fire on prod to make them realize their error... if that's the only way they are able to learn, it's going to very rough for their career, their team, and any org they're working for.
