I am considering working for a branch of a government that imprisons citizens without trial (let alone assassinating them at a distance).
Does it matter if I work for a different branch? Does it matter if I don't work for the government but I pay taxes that support these activities? Does it matter that the work will happen (perhaps for the worse) even if I am not involved?
What if I work from "within the machine" to help other citizens? What if I work from within the machine to overthrow it? What if I just want to make money to retire on a beach and don't care who dies?
Where is the line? Does it move?
