His dudeness
There is a world of difference between victims through collateral damage of a bombing raid a few miles away from the target & targeting civilians through machine gun boresight & intentionally strafing them.
I would say that one is Accidental Death as the Dambuster crews weren't deliberately targeting the Polish prisoners, whereas the Stuka pilots were just murderers hellbent on following their orders to kill & maim every living thing on those roads- civilian, combatant, male, female, young, old, man woman & child.
But then again, I am British. And let's not forget who was responsible for those poor unfortunates being in those camps.
I can't believe you compared the Dambuster Crews to Stuka Crews. You have a remarkable take on factual history.
