This is like the contractors working on the Death Star when it was blown up.[1] They knew what they were working on. They knew the dangers. Can't cry for them when they're blown to smithereens.
I've been asked on two separate occasions to work on some crypto startup idea. Aside from my skepticism that they were even worthwhile projects, I declined because hell no I'm not writing code that touches other people's money.
In the real world a lot of army is conscription. Typically it not freelance mercenaries it can also be prisoners or threatened/coereced labour. Star wars actually highlights this in Rogue one.
Also in many economies this is literally only job available, same reason why syrian fighters are ready to go to Ukraine.
