Building part of a killing machine isn't really something you can defend, even if you weren't working on the part of the machine that does the killing.
What part? If you work on the manufacturing line for bolts, and one of the ten thousand bolts your company makes is sometimes used in cruise missiles, are you a munitions worker?
I think you're likely trying to say "the guy who wrote the positioning code" is as much a killing machine maker as the guy who loaded the explosives.
We all live in glass houses
Do me a favor. Go to Ukraine with someone who worked on the Javelin anti-tank missile and tell them that. I bet the guy who worked on the Javelin will be considered a hero. You will likely receive a kick in the balls for ever daring to criticize him or repeating your post. Your take is naive in the extreme.

Of course it is. I don't personally have an issue with folks who worked on weapons of war. Particularly if they're honest with themselves about the work they did. Doubly particularly if they felt a sense of mission in it.
And in an integrated culture and economy, the difference between a person who happens to work at a company with an evil project in a random division and a person who grows complacent about politics with their non-problematic job is thin to the point of vanishing.
