Itachi killed his family, he has reason enough to be sad. <(-.-<) Also Sasuke is his brother, who wouldn't be Emo ?Itachi is just emo, dont question the emo.......................
That was just the tip of the iceberg, torturing and mindraping your baby brother into a psychopath and forcing the Uchiha's curse of hatred onto him just so he'd get stronger and then mindrape him back into a good guy doesn't seem like something a loving brother would do either.i know that itachi was good but why did he tell sasuke to kill hes best friend to awaken his ms this doesnt look like something a good brother would do...
