If you're going to share the airspace with me, I bloody well do expect you to fly by the rules, especially if you're being paid to do it. Just where would you draw the line regarding regulatory compliance? Would you fly a trip with insufficient crew rest just because you need the money? How about busting mins for the same reason? Carrying one more passenger "off the manifest" in order to make an extra buck (I know one former 135 pilot who burned one passenger horribly, and almost died himself doing that)? Maybe flying into known icing conditions hoping you won't ice up your non-FIKI airplane?
If you're going to fly for hire, there are a couple of words you should look up in the dictionary: "integrity" and "professionalism". Either you have them, or you don't, and if you don't, please stay on the ground so you don't kill someone.
