If you believe (and told so) that your aircraft is protected from stall, you may not avoid it as actively as if you know it can kill you…
Bravo, the essence of the problem leading to these fatal accidents in a few words. (but let's wait for the data, to be sure)
You may not avoid it as actively and you may not know how to recover from it.
Bottomline it is difficult to say, if the computer protection has saved more lives than its presence has lured management and pilots into negligence regarding their skills of handling the aircraft at the borderlines of aerodynamics and costing lives in the process.
