No. It seems unlikely that the drone pilot would have all of that information beyond where the target was, that would be necessary to make an informed decision about participating in an extrajudicial execution of an American citizen.
From my experience in manned operations, you're basically only given a target, not the details.
Based on that, I would assume the targeter did not know whom they were targeting. Or they did, knew the orders came from the National Command Authority[1] (Eg. POTUS) and did it anyway. I would have.
