Walter, what puzzles me with your line of argumentation is the single minded focus on the pilots behavior and ignoring everything else including the fact that we know training manuals were inadequate and MCAS proofed to not be airworthy. As the still missing FAA and EASA certification shows. Including one near crash during simulator flights, conducted with an updated MCAS, hyper-trained crew that knew more or less what would happen in a protected environment.
