Nobody is talking about indiscriminate murder of randomly picked civilians out of spite. But when those civilians are the machine that drives the war, they become part of that war. That is why in a total war between nations you send hundreds of planes to carpet bomb relevant cities (incl. their population) to cripple enemy nation's ability to keep waging the war against you. They are not sent to bomb ski resorts or villages where nothing happens.

Do you consider someone that puts together IEDs for someone else to deploy an untouchable person that your need to leave alone? This person is unarmed, he's not a combatant, he's no threat to you, he just googled how to put a bunch of stuff together.

I know for myself, that if i find myself in the middle of a war i don't believe in, i'd pick my shit up and leave immediately, go anywhere else. I wouldn't just stay where i am, coding my web apps next to a goddamn bomb factory or HQ of some kind in complete denial of my surroundings, the current situation, and reality itself, while bombs are being air mailed to said factory/HQ next to me. But if chose to stay either because i want to be part of that war or am simply clueless, i can't blame anyone but me for the situation i find myself in.
