Crowds can grow used to atrocity
Public killings can become a spectacle that ordinary people attend and watch. An outsider is sickened, and is left asking whether the watchers have simply stopped feeling it.

Trauma surgery in war zones requires improvisation when equipment, time, and safety collapse.

Surgery gives one person great control over another's body. That control is a power to help and heal, but it can also become attractive in its own right, apart from the good it does.
Flying a skilled outsider into a catastrophe helps only for as long as they stay. The lasting fix is to teach the doctors already on the ground how to treat the injuries war causes, so the skill remains after the visitor leaves.
Someone preparing for dangerous work should build skills around the injuries that work will actually bring. Bullets and bombs mostly kill by bleeding, so a war surgeon needs broad general surgery plus the vascular skill to clamp off damaged blood vessels.
The urge to rescue people in danger is often mixed with a hunger for danger itself. The same person can be driven by compassion and by the adrenaline of risk, and admitting the second does not cancel the first.
Austere settings strip away the equipment, backup and safety a surgeon normally depends on. What remains is a test of self-reliance, and some people find that challenge one of the work's main rewards rather than only a burden.
In long conflicts, violence against civilians can turn into sport with its own rewards and rules. Snipers were reportedly paid in cigarettes for hitting particular body parts, and one began targeting pregnant women.
A doctor sworn to treat all wounded may find a patient from the very group that wants to kidnap or kill them. Keeping to the principle then costs real fear, and the same group may later try to take the doctor hostage.
Facing mass suffering again and again builds up until it overwhelms even a seasoned professional. The result can be collapse and lasting psychological injury that needs treatment for post-traumatic stress.
Those who see the damage war does to ordinary people take on an obligation that reaches past treating them. They are bound to make others aware of what modern warfare does to the people and communities it hits, and to act beyond the operating table, for example by helping arrange civilian evacuations.
