Boeing's expectations for pilots recovering from an MCAS error were criminal. With an erroneous AOE reading, MCAS would immediately and repeatedly force the nose down. Pilots, not even told that MCAS existed, would somehow need to quickly recognize it as a powered flight control problem, cut off power to the stabilizer, and use the manual trim wheel to raise the nose - which can be physically impossible at high speeds in a nose-down attitude.

No rational person would think this system wouldn't kill people. The people responsible committed manslaughter.
