What's with so many of these comments being flabbergasted that there's a switch in the cockpit that can cause harm to everyone on the plane?

Do you realize you're entrusting two people in the front of the plane with your life as soon as the plane takes off? There are probably DOZENS of switches that if they are flipped maliciously will result in everyone on the plane dying.

I think the difference is the that those other things affect everyone on the plane, but depressurising only the cabin, doesn't.

It also impacts the pilots (they don’t have their own pressurized area, it’s the same), but the pilots have more oxygen. Which is a really good thing 99.999% of the time.
