Agree completely about prevention.
Ultimately it comes down a pragmatic view of what is achievable.
Rear facing seats (although some authorities are unconvinced), smokehoods, sprinkler systems etc etc etc may, under certain circumstances, save lives or serious injuries, but the cost is prohibitive and commercially unjustifiable as those events happen so infrequently.
I also agree about the human factor; Chernobyl reminds me of the capacity for people to cause disaster by deliberately overriding safety mechanisms.
Airlines tend to profile their crew very carefully to avoid the above syndrome.
