I doubt it people in the bronze/iron age were used to people dying violently. Goliath was a soldier who agreed to a fight to the death it's an occupational hazard
i taught 9/11 to history students who weren't old enough to remember it. i put together a reader of pre-attack context, and OBL's letter to the american people. oh and we watched that one video of the cranky new yorker in one of the towers talking to emergency personnel up until the building collapsed, cuz you know, the human element and it makes me sad.
by comparison, on the day bin laden was killed, i had a coworker who cancelled all lessons for the day, dressed in flag apparel, and just did patriotic riffing for every period.
