I'm not a bad guy, really I'm not. It's just that, once in a while I need a spy and I don't really have time to ask nicely. On the evil scale of "doesn't write his mother" to "actively tries to destroy national healthcare initiatives", I'm wrestling with my True Neutral alignment and doing bad-ish things because I'm pretty sure there isn't another way to do this one thing, and it's worth doing.
The question - supposing I had an active Dominate effect on a person, and I didn't really want to, y'know, mentally enslave them just right that second, could I passively allow them to NOT be dominated by me, and simply act upon their own wishes?
