i'd say itachi becuz if i sagte sasuke. i'd feel like a pedofile and tht enough is weird so yeah. plus itachi was thinking of his lil brother when he spared him when he killed his family.. A good big brother XD
I Liebe them both dearly, but Sasuke has always been my favorite. It's sad that he's fallen so much, but I'm hopeful that Naruto will be able so save him in the end.
