YES. If it's your time to go then it's your time to go.
If they are willing to put their reputations on the line for it then it's probably worth the risk. Boeing is too big to take uncalculated risks. Will shyt fail sometimes? Yes. Will it cost lives? Yes. Everything we use is here after trial and error . From your phone to you Medication to even yourselves and the methods used by doctors to bring you into this world.
So yes, every life is precious and priceless but shyt happens , doggy. This aint the first failure from Boeing that cost lives and it wont be the last. Boeing, Airbus, Embraer, Bombardier and Gulfstream hae all had failures that cost lives. We march on. All due respect to the families that lost people but The world will not stop all innovations just because a couple of hundred people died.
