I really dont think i want to imagine Sasuke any other way... he could be this happy go lucky guy that smiles all the time, or over time he could end up the way Itachi did and maybe he would end up destroying his clan considering how well itachi did and how quickly he mastered his skills... Maybe Sasuke would go all psycho with jealousy and well you know... But I like him just the way he is now... he he ^.^
