Are you ill in the head? WHY would Sasuke use his EMS and fight against his brother? He loved his brother and it's because he loved him so much that he's doing what he's doing; to get revenge on Konoha for what they did to Itachi.
Actually it was Itachi,Sasuke hated Itachi wanted to kill him and avenge his clan.Remember!!
Thats Sasuke Story through this whole series.
He now knows what really happened so hes blaming Konoha now.
but.....
Theres still a chance Sasuke hating him for actually following Konoha Orders rather than choose to protect the Uchiha Clan his family.
Sasuke is blaming the Village but in the end his brother had the last say.
'People dont change overnight' i know they eventually do.
when he faces off with Naruto
like itachi (to naruto) said 'im glad my brother has a friend like you'
