The point that I'm trying to make is that the point of view of a trauma surgeon in a war zone is biased, not because they're bad people trying to spread propaganda but because they have a filtered view of the war: They're seeing a subset of the casualties.
You don't treat dead people in a hospital during a war. They don't get taken to hospital. You treat people "just hurt enough" to require surgery, but not so much that they definitely won't make it with or without surgery...
... such as single gunshot wounds to the head, which are surprisingly non-fatal. There's many(!) stories of people trying to kill themselves by shooting themselves in the head and failing.
The stories told by the people in the article are anecdotes by a select group with a strongly statistically biased view of the world on top of a personal bias against a literal enemy at war with them.
They're probably not wrong and they're probably not lying, they just can't see the whole picture and can't possibly know what an Israeli soldier is thinking our doing at the front line far from the hospital.
