I disagree, slightly. We have to expect some degree of ethical behaviour from everyone, even those who nominally have no room to manoeuvre. If everyone in such positions were to disobey unjust orders the orders would eventually have to change.

Walking away stewing in rage does nothing except fill you with damaging hormones.
