Itachi slowly walked towards his outouto with a slight smile gracing his features, Well if you called blood and cuts all over you Grace then yes it is grace. When he made his way towards his brother he had a flash back.
*FLASHBACK*
A very upset five year old Sasuke had walked up to his older brother and pouted in a childish way. "Nii-san you said you would watch me practice throwing kunai today!" Itachi chuckled looking at his younger brother and gestured Sasuke to come over to where he was Sasuke smiled and ran right over to Itachi but tried to retreat when he noticed his Brothers hand went up and flicked him right on the forehead "Sorry, Maybe some other time sasuke' said Itachi sadly.
Sasuke frowned and stuck his tongue out at his brother "I'll just tell Kaa-san that you don't want to watch me, and then you'll have to' said Sasuke running off to the direction of their home. Itachi sighed but thought to himself that it was always like this and that Sasuke was like this and he liked it like that (LOL so many this and that's) Sasuke entered his home as well as Itachi once he arrived.
"Kaa-san, Nii-san doesn't want to watch me practicing at throwing kunais!" boomed Sasuke in a fake upset tone putting on puppy eyes. "Itachi promise you'll watch Sasuke tomorrow, okay?" said his mother more demandingly then questionably. Itachi nodded and just smiled at his little brother.
The Next Day
Everyone did their morning routine getting cleaned going to school going on missions etc. and Itachi received a mission to do around night fall and he mustn't fail for the sake of his brother. Once he arrived home everyone was already back and it was about night fall so he decided to start his mission except sasuke wasn't there yet.
Itachi slaughtered every Uchiha and finally stood before his mother and father "Itachi we know this was your choice, If you think it's right then go ahead" said Itachis father sadly. "Itachi remember we love you" said his Mother as she cried tears streaming down her face 'this'll hurt you more than the pain we are going through my precious child' thought Itachis Mom.
Itachi thrusted the blade into his parents heart making a quick kill but it wasn't clean or peaceful;, sadly. Just when he'd done so little Sasuke was before the door with wide eyes "BROTHER WHO DID THIS! WHO KILLED MOM AND DAD?!" Itachi looked at his little brother and trapped him in a genjutsu. "Foolish little brother I have massacred everyone. Go and cling onto life like the pathetic person you are." said Itachi slightly weak because it pained him so much to say so.
"NII-SAN STOP SHOWING ME THIS!" screamed sasuke as he saw everyone he cared for die by the hands of his… brother. And at that moment he decided he'd be an avenger. Once he was out of the genjutsu Sasuke ran away, While Itachi hid watching Sasuke.
*END OF FLASHBACK*
Itachi finished his thoughts as his smile remained on his face "I'm sorry I caused you so much pain…. Sasuke" spoke Itachi as he put two finger onto sasukes forehead and fell over. Those words being his last. Sasuke stood there wide eyed as he slumped to the ground and began to sob while the rain poured, and for a second it seemed to be tears of Itachi that were pouring.
