I don't blame them -- I've never been in a wildfire or imminent disaster situation, but my impression is that the majority of the people who've died in the fire didn't die because they were completely ignorant of the fire until it was suddenly upon them. They are aware of the warnings, but don't believe until it's too late that they are in imminent danger. So I don't think the victims as being particularly irrational, just particularly unlucky.
I've watched this video, and I've seen it shared frequently with people highlighting exclusively the "dumb" woman and her makeup, as if that seemingly superficial decision by her was the thing that led to her tragic death. There were others who died at that gate in the fire, and they all made decisions just as superficial as wanting to put on makeup beforehand -- I mean, in the way that every delaying decision is incredibly superficial when we consider it in retrospect.
