And if I were hiring, I'd certainly think less of you for taking that stance.
Picture this: we're deep in the Cold War era, and Ronny Raygun is the president. The Star Wars initiative is in full swing. Nuclear mishaps and near-misses are still an all-too-frequent occurrence. Nena's red balloons are ready to fly. The President has just gone on the air and promised to "Outlaw Russia," and that "The bombing starts in five minutes." Some officers from the Pentagon approach your company's management and ask them to bid on a project that will involve launching dozens of military satellites equipped with atomic clocks, designed to locate any person, place, or thing on Earth at meter-scale accuracy.
Do you threaten to quit the company, lecture everyone who will listen about the potential for misuse of such dangerous technology... and miss out on the chance to contribute to GPS?
Or, how about a few years earlier, when they ask you to work on a colossal air-defense computer system using technology that hasn't even been invented yet. They want to use computers to vector fighters to intercept approaching Soviet bombers, and to target missiles to kill the ones the fighters miss. It's obvious to anyone not in uniform that the whole idea is insanely stupid, wasteful, and destabilizing. They want to spend $50 billion to develop a system that guarantees one whole 'nine' of uptime, that can be trivially jammed or disrupted, and that will literally be obsolete the day they turn it on since it can't deal with ballistic missiles.
So you tell them, "No, I don't want to work on SAGE. Peace out and fuck off." As it turns out, the system is indeed useless at its stated purpose. The spinoffs, on the other hand, not only revolutionize the entire IT industry, but create it. The next thirty years' worth of progress in computer architecture, memory and storage, networking, display and human interaction, and fault-tolerance is traceable directly to this boondoggle. All of these things would probably have taken decades longer to evolve without military funding and backing. Nobody dies as a result, but a bunch of your coworkers do get to play with a lot of cool toys.
Then there's the whole ARPAnet thing, funded by DoD to survive nuclear holocaust, asteroid strikes, plague, fire, and famine... any threat imaginable by anyone other than telecom-industry lobbyists.
Even the very wise cannot see all ends, and that goes for modern-day hippies too.
