Soldier vs Doctor?

It is reported that fierce battles are continuing in Ukraine, but as I imagined, misfires of friendly fire, accidental explosions, presses, etc. are also targets of sniper. Even if it is a　TV lens, if it is recognized that they are aiming for the opposite, they can be sniped without hesitation.
Air raid sirens rang and disguised soldiers were confused, and the battlefield was probably at the height of confusion like a crucible of hell.
The vivid image of the scene of such a desperate killing that took a life is really scary because the collision of human energy exposed to the limit is transmitted, which is unthinkable in a peaceful world.

Both of them are really sorry for Ukraine, where he has become a field of combat with new slaughter weapons devised in various ways.
Can anyone be a crazy human who has lost reason and dignity and exposed his ugly animal instinct?
But even in the civilized society of the 21st century, it was proved that once the war started, it would become an awful carnage anywhere in the world.
We should have learned enough from past history, but will he repeat again?
Will the war that arises from the struggle for hegemony eventually explode the stress of balloons that both sides have accumulated, and will he have to do everything?
Unless we break the chain of stupid hatred, miserable sadness will be repeated.
It's very strange that soldiers and medical doctors exist in the battle scene together, the former try to kill and injure and the latter try to save lives?
