You seem to have a problem in logic.
Given 2 choices A and B; each with risk of injury/death to passengers the captain makes choice B based on external expert advice and risk assessment with the known information.
At the time of the decision it is unknown whether that decision will be right or wrong.
The choice B made leads to no injuries to passengers.
Looking back (hindsight) the decision not to evacuate was the correct one. It was not known at the time (foresight) if the decision would be correct or not.
