What an idiotic whataboutism that has nothing to do with my main point. Because people who work for morally ambiguous projects might also be proud of their professional work, nobody working on anything else should be? Or what are you saying, because it seems a bit muddled.

Also, to answer specifically to these folks, maybe they shouldn't be morally, but if it made them personally proud, as far as quality of life FOR THEM personally goes, it's still a valid example. Morality and personal happiness aren't always directly connected in some people.
