I am not quite sure the question here is the right question to ask. Did lucas Betray Padme? Uh, no not quite. Lucas was not part of the story, padme was. Thereby from deductive reasonsing, there is no possibl way Lucas could betray Padme. You see, this nice kid who went completely nuts by the name of Anikin Betrayed Padme. I would even also say Palpatine betrayed her as well. From her point of view from Episode 1, Palps was supposed to be her friend and on her side, and what does she get from it? 3 attempts to kill her. What a great friend he was phooey.
