Boeing made many mistakes. Greed over safety.
“In creating MCAS, they violated a longstanding principle at Boeing to always have pilots ultimately in control of the aircraft,” said Chesley B. Sullenberger III, the retired pilot who landed a jet in the Hudson River. “In mitigating one risk, they created another, greater risk.”
"Even Boeing test pilots weren’t fully briefed on MCAS."
“Therein lies the issue with the design change: Those pitch rates were never articulated to us,” said one test pilot, Matthew Menza.

Software developer and pilot's comments.
"It is likely that MCAS, originally added in the spirit of increasing safety, has now killed more people than it could have ever saved. It doesn’t need to be “fixed” with more complexity, more software. It needs to be removed altogether."

3 airline pilot's response
"As an industry expert, I have flown the 737 max as a line captain and it was my 12th type rating. The MCAS is the tip of the iceberg, this airplane is majorly flawed not only aerodynamically but also technically.
Never before have I encountered such strange behavior from an airliner."

Another critical software flaw was found regarding the flaps. Boeing only checks for errors after crashes now? What else is wrong with it?
How many other "flaws" are there that haven't caused crashes yet?
Boeing workmanship is so bad on the Air Force's new tanker aircraft that they have refused any more deliveries. Tools and parts were found left inside sealed areas of the aircraft. Garbage has also been found in brand new 787s, including a ladder that could have jammed the tail. Qatar Airways has refused delivery. Have the Max aircraft been inspected for garbage?

A Southwest 737 Max had an engine failure as well and had to make an emergency landing. They were just trying to move the empty plane. CFM engine overheating and failure is another issue.
Southwest had a deal with Boeing that no training would be required for the 737 Max or it would cost Boeing $1 million per plane. That explains why the bad aerodynamics and MCAS was kept a secret.
