I know! They're brothers after all!I've never really liked Sasuke x Itachi either. ^^;;
I don't think he has ever hated SasukeI wonder if Itachi really did hate his entire clan (with the exception of the best friend he killed and Madara Uchiha)...
Though, Orochimaru was sure outstanding in training Sasuke. But it's mostly Sasuke's own ambition that made him stronger then even Orochimaru now.
