If babies with bullet holes in their heads don't spark sanctions, why should this?

They probably removed part of his skull. He would need to wear a helmet 24/7.

Usually after healing is complete a synthetic skull is made to replace the lost one. I think sometimes they can put the removed piece back in.

There are reasons to remove such a large section of skull. But I'm not a neurosurgeon. I am however a neuroscientist and I've seen this as a procedure for rare and extreme brain injuries and infections.

The brain has many layers of tissue around it including a thick leather like shell that holds in the fluid. Dura mater (hard mother).

This is part of why brain surgery is so risky. Any invasive techniques makes openings in this casing. And if the casing isn't "water tight" , bacteria can get in. Liquid can leak out. Which can cause the bottom of the brain being suctioned into the spine. Yeah it's as bad as it sounds.

This fluid that surrounds the brain is the same in your spine. That's why loosing too much will cause the brain to be pulled down into the spine. (Similar to Chaiiri malformation.) https://www.wikiwand.com/en/Cerebrospinal_fluid_leak

You get any infection in there and it's going to travel down your spine too.

But it's going to destroy your brain so .

Your brain is a special organ in that it's essentially cutoff from the body in many ways. This is to protect it.

Even blood is a neurotoxin and will destroy brain cells. So oxygen is fed via capularies in vessles. Big enough for o2 molecules but not blood cells. This is the blood brain barrier you hear about.

Any bleeding in the brain doesn't just result in some area being starved of oxygen and neuron cell death, but it can destroy surrounding tissues. Permanently. Neurons don't grow back.

And as I said the brain is closed off. And because of this design, it has limited abilities to fight infections that do get in. It's Difficult to clear out proteins that might build up or bacteria. Parasites. Especially if someone is immune compromised from starvation, extreme stress, other health problems, steroids. There is an ameba that can basically consume your brain in 10 days if it gets in. Even if you are at peak health. The ameba don't do shit in any other part of the body because your immune system kicks it. But not in the brain. https://my.clevelandclinic.org/health/diseases/24485-brain-eating-amoeba

Think of it like the human eye. (Which is technically part of the brain).

You can cut into an eye safely with modern tech. (Cataract surgery But these are highly sophisticated,) But it is filled with fluid. Fluid that's semi permanent. Meaning contaminants stay forever bumping around. Destroying the retina. No way for the eye to clear it out. The sclera can heal a bit better than other parts of the eye (white part of eye) but you understand what I'm saying about it being a closed off organ with liquid that must be maintained.

That's a good way to think about the brain.

Imagine cutting into the side of the eye to drain a rupture while trying to repair the casing (dura matter) to the point of being water tight. But maybe with a drain tube for blood ruptured area.

These surgeries don't usually work out. Usually the person dies from infections.

Not to sound pessimistic. But there is a high chance of that for this guy. Especially considering his health state.

Unfortunately, it only looks like some of the worst atrocities of the 20th century, aka the 1900s. If you look back to the 1800s or previous it looks commonplace.

To the west and their allies it's only barbarous if they killed any of their precious race. Everyone else is fair play.
