'so experience but sub standard SQ captain didn't evacuate despite raging fire on wing..... should have not listen to fire chief but listen to you arm chair captains.....then maybe ... just maybe everybody might walk out of this alive.....oh hang on... that happened. '
The issue with this is the Normalization of Deviance - It was successful this time, so with hindsight we think it was acceptable despite being against accepted procedures.
The difficulty is that there is a very fine line between an event such as this and total catastrophe - where all 280+ passengers could have ended up in a very bad way in a very short space of time. There are far too many real world examples of this happening, unfortunately.
So unless there is a very pressing and very present reason NOT to evacuate, the choice should always be TO evacuate. The downside is that to prevent the unthinkable from happening, we do need to accept the slight (comparative) risks such as sprains, breaks etc that come from performing the standard evacuation procedures. They will be far more preferable than deaths and serious injuries.
