Elite is the type of game where there is no good or bad people just bad decisions.
Even pirates could be smuggling goods into a planet in order to help the population so I feel that for every type of mission that there should be a counter mission for someone to take up if they wish , for instance there will be plenty of passenger transportation missions but every now and again you will get an assassination mission (against npc rather than players) or halt their progress so that they don't meet their deadline (mainly against players) etc
Are there any missions that shouldn't have an opposite associated mission? - I can't think of any, it just depends on what direction you want to go.
