This assumes Boeing had a priori knowledge that the system would cause a crash. The fact that the system safety analysis didn't label it 'catastrophic' seems to indicate they didn't know this. This doesn't absolve them of the responsibility that they should have, or that they still didn't follow their design procedures stating redundant senaors
“I didn’t KNOW removing three of the four brakes on my car would cause a crash” is an argument you could make. I wouldn’t want to stake my freedom on it.
That's assuming you are making a connection between brakes and a catastrophic failure.
The fact the system safety analysis didn't call out an MCAS failure as catastrophic seems to indicate they misunderstood the system risk which is different than claiming a catastrophic failure is an acceptable risk
