Because many of these people see it as a fun hobby, they don't spend much time worrying about potentially being ordered to drop bombs on schools filled with children. It's rather unlikely that their government would order them to do so anyway, compare a list of countries being hit by Iran with a list of countries bombing Iran.
Anybody who ever went through arab countries with eyes opened saw the massive nepotism and corruption at all levels. Army/air force ain't immune to this, in contrary. Do you think ie some general or politician's first son would be treated and pushed up same as common folks?
In the case you're presumably referring to, no fighter pilots were involved. A Tomahawk missile was launched from a US naval vessel, aimed at a military site next door to the girls school.
That was a launched cruise missile from a ship, targeted by an LLM. Apparently the grounds USED to be a valid military target long ago (a decade? I'm not sure exactly) and now there's a school there.
I don't think it's a known fact at this point.
1. A LLM did the targeting
2. Targets were selected and evaluated by humans and the many-years old change of building shape and purpose didn't get caught during target eval.
Ted Bundy drove a car. Cars kill people. Doesn't mean that Ted Bundy was killing people by running them over.
Building an LLM is one thing but building one specifically to pick targets is another.
For me knowing that my actions may have contributed direcly to the death of anyone is not something I want to live with.
