No Lelouche never fought for power or anything like that,... mind u but he was fighting against an empire that had an ideology that was nothing short of Hitler's, numbering people(taking away every self respect they have left) , exterminating whole city's, the difference between him nd Lelouche is that he took control of the situation , he was the driving force of the Black Knights and the liberation of the "enslaved " people by the Britannian's empire, Itachi was more like a pawn compared to him
