If you really believed these labs were going to result in the extinction of humanity and you saw it first hand, don’t you have a moral obligation not to quit your job but to go and try and kill everyone working on said project, blow it up, or otherwise stop it?
I take these resignations with a grain of salt precisely for that reason. If I worked at a job and I saw some crazy guy or gal was building a doomsday button and it really worked I’d like to think I would do something about it, not just quit my job. If you’re not going to actually do anything about it you might as well keep your job. Quitting doesn’t help anything.
