Mordred has NEVER shown signs of wanting power, or the throne. So I definitely doubt it. He just wants revenge for the execution of his friend!

@Knightofthecart: I think that Merlin betrayed Mordred as a fellow magical being. He did it in the Disir, in this one, in the whole of series 5, heck, he almost did it in season 1, when he almost let the boy be executed.
