There definitely has been a level of war voyeurism on social media for the past several conflicts.

Gratuitously watching people die, I suspect, won’t really change anyone’s vote, or to volunteer, or donate. At least long term, because the violence usually is the attraction, not the conflict. And there will always be a new conflict.

A few key events in history have happened because of, lets say, acute exposure. But chronic exposure, to your point, possibly makes our judgement worse.

As an example, “The Terror of War” turned many people in America against the Vietnam war.

Maybe the existential horror, disgust and impotent rage building in the zeitgeist of American youth will make music good again.

It can be something relevant to seek out but wouldn't use the word desirable at all. It may improve judgement but hopefully serves better to improve humility and gratitude.

The benefit is if you show people what war is actually like, people will be more averse to it

War is entirely different when it goes from "Jimmy heard that bombs were dropped on a hospital" to "here is a hospital where bombs are dropped. Here are the people trying to pull family members and the dead out of the rubble. Here is a cat feasting on the remains of a deceased person because there's no food in the area. Here is a man throwing the body parts of his child into a duffel bag so that he can bury them according to his religious customs."

War is a neat little 3 letter word. The brutality that war inflict should be mandatory viewing so that we know what engaging them costs regular people.

It's different, but is it beneficial?

Of course it is.

Everyone should learn how the sausage is made. It makes it far more difficult to brainwash you with jingoism later on.

I have absolutely no scientific basis for this, so take my take with a giant grain of salt, but I would be afraid it desensitizes people to violence or just traumatizes them, especially if they're kids. There's a reason you don't show the new Evil Dead movie with a zombie using a cheese grates people's eyes to children.

People, that means the kids parents, are not voting for horrific zombie enabling politicians, but it’s in their hands to stop supporting the war-hawks.
