yeah he actually passed on all his skills to sasuke and
activated an amaterasu to try and kill madara..
the speculations was right afterall, itachi was forced into it,
and the reason he made sasuke hate him so much was for him to grow
stronger and do what he himself couldnt do.
n most likely he was weaken prior to the fight with
sasuke... else he wouldnt hv job so easy to sasuke...
somehow now kinda feel tat the whole fight, itachi is jz
showing/teaching sasuke wat the MS can do...
