Just because you don't feel that way doesn't mean they're all wrong.
any sane parent would think twice risking his life over a THING. risking life to save other (strangers) lives it's questionable, risking life to save things it's just stupid
There's nothing unusual for being willing to die for a THING. Hell, people have sacrificed themselves in the millions for mere ideas. People fight to the death over tiny scraps of symbolic land.
It may seem stupid to you. It's stupid to me, too. But that's what people do. That's what people are.
as for saving someone's else child I would most likely not do it if I would calculate it's too risky for me (unless I would be stupid by instinct), if their own parent/guardian font care about their lives why should I? I don't expect other people saving my children. though it's not fair comparison,I am sure you have minute to decide if you save some piece of art work compared to split second decision to save living being
I also worked in past in insurance companies, after dealing with thousands of accidents my advice it's always run over animal, don't try to save it by avoiding it (unless it's boar or something similar comparable to concrete block/tree), try to fight your instinct, saw way too many dead people or in serious injury because they tried to save some stupid dog/fox etc and then crashed into some tree/building etc
If entering a burning building (which isn't actually _that_ risky) to salvage one-of-a-kind historic artifacts isn't something you would chose to do, that's fine. Don't label the actions of those that make a different choice "stupid".
