Was the mass coordinated mutual killing at Masada (for lack of a better term) an act of heroic martyrdom or immoral murder and suicide?
While it is unknown for certain what exactly transpired, according to the only recorded history of it, nearly 1000 Jews withstood the Roman occupation of Judea, and attempted to fight back, by retreating to Masada and setting up a military outpost and refuge there, until they were ultimately trapped on the mountaintop. In the end, 10 men were selected to kill all the others, and one of them was selected to kill the 9 remaining men and ultimately kill himself at the end of it all.
On the one hand, they were likely trying to prevent torture, murder, rape and pillage from befalling themselves at the hands of the Romans.
On the other hand, who could say for certain that the Romans would have done that to them? Furthermore, if they had negotiated a peaceful surrender (especially if they hadn't first engaged in attacks but truly acted as though their retreat to Masada was for purposes of refuge from the war rather than a military strategy) they likely would have been taken as captives and perhaps enslaved but not specifically tortured or killed.
Much ink has been spilled on the subject of martyrdom (LeHavdil from the oceans of blood that has been spilled in actual martyrdom). What can be inferred, from that literature, regarding the specific case of Masada (assuming the story as generally understood, as summarized above, is what actually transpired)?
