Do you have any idea how many completely uneventful flights Falcon 9 vehicles have flown? The most recent version (the FT which had its first flight in 2015) has had precisely zero failures across 254 launches.

They have a better safety record than any other launch vehicle in history, including the Saturn V and the Shuttle.

The deaths stemming from those programs have held back interest in manned space exploration more than any failed test flight ever will.
