I think there is a bit of a difference, just because the only reason one has a job, ostensibly, is to get money so one can feed themselves and others. Usually signing up with a military has more to it. But, even in those cases, the US Soldier's Oath I know explicitly includes an oath to never follow an illegal order. And we found out during the Nuremberg Trials just how dangerous it is when people put their head down and say 'just following orders'. Every human being is given the ability to control their own actions, and that responsibility can never (OK almost never, humans are complicated, one might argue soldiers that are trained to the point of killing on reflex and who then get PTSD from seeing their body do something their conscious mind would never permit before it can intervene might have a case) be given up.
