A better analogy would be if you found out your favorite drink gave you a 100x greater chance of getting pancreatic cancer, would you stop drinking it? (Note: the odds of you getting pancreatic cancer on the whole are still immeasurably small even at 100x) What if you found out this new drink recipe never went through any safety testing but the company claimed it was basically the same as the old tested drink you enjoyed previously from the same company?
Even if my chances of dying on a 737 MAX are much higher than dying on a tried and true A340, they are probably around the same as me dying from pancreatic cancer and I don't get my pancreas checked regularly.
