What a disgusting attitude you have.
Imagine if somebody invaded the US because they didn't like the Biden administration. In the process they kill your family, but don't worry, it's just civilian causalities during a war.
Shit happens.
Here is another reversal comic/satire about killing civilians:

What do you call it when you kill, in the name of saving lives?
That said, do we really want a world like this? Because logical conclusions of it are not fun. It is not like I can wear 'I am innocent' flag. And clearly, not that anyone would respect it.
A world when everybody must prove that is innocent, so is not executed at first sight by a machine is terrifying. And as long as people starts seeing preemptive murder as a good cheaper alternative to justice, the fall is unstoppable. We really want to live in that world?
These are civilians minding their own business. You don't get the right to murder them just because you are fighting nearby with some other group of people.
If that most basic of human rights is not protected then nothing is.
You might maybe be able to excuse civilian causalities in some total war scenario where your own safety is literally at risk. But that is very far from what is happening here.
Translation - lunatic politicos bought by a bunch of rich greedy bastards starting wars with countries that can not properly strike back. All for the sake of control and money.
