It was Boeing management that wanted MCAS, and wanted it exactly like it was originally designed, so that the Max 8 could operate on the same type certification without additional pilot training or simulator time. As a result we have 350 dead. If the original iteration of the user manual obfuscates MCAS and its role, and the pilots don't receive specific training to deal with it, I just can't see how it's justified to pin those accidents on the pilots. So, it was "corporate executives", motivated by financial considerations (AKA "greed") that made the call which lead to two preventable disasters. That some air crews managed to identify the issue cannot absolve Boeing upper management from their responsibility. That the FAA permitted the manufacturer to self-certify only adds to Boeing management's responsibility.
