And? I used to work for a defense contractor, using the military complex money to instead pay for civil projects that actually benefit normal people. You can take money that comes from "I don't like this thing", and then spend it on "this benefits everyone".
If that's truly your rationale then you're deluding yourself: you can take money, for sure, but as soon as you act to aid the source of the money then you're complicit in whatever that source is doing.
You might consider the positive aspects of your use of the money out with the negative aspects of your aiding murder, say, but that's not quite what you outlined.
And that's why everyone who works for Google or Facebook should quit, too, but in the real world there are an insane amount of jobs that ultimately do really bad things, and we need work. So find somewhere that your particular skillset makes a net positive contribution instead of going homeless because almost every single big company is responsible for suffering in the world. The defense contract I worked for also has a strong civil presence and makes things like turn stiles, card readers, and emergency alert systems, and those directly benefit people rather than help murder folks. The idea that "my work directly benefits the part of the company that murders people", given how budgets actually work in large companies, is arguably far more delusional here.
Does the defense contractor rag on the military afterwards? You can take money from something, use it for good, but it's kinda funny when you start to claim the hands that feeds you is evil and bad.
