Autonomous drones are indeed forbidden by the Geneva Convention. I'm on my phone and cannot easily link to the relevant passage, but will later if anyone asks.
Regarding the morality of drones, I consider them equally moral -- or immoral -- insofar as it is delivering conventional munitions. I believe that the morality of conventional weaponry is tied to usage and intent, much moreso than delivery system.
