Not Quite yet, no definitely not yet!

(Deep inside John's Subconscious)

He's Fading fast, I will not allow this one to die, not while I am here inside of him! Says the Nine-Tails inside of John, who releases a karge amount of his Chakra into John's Body.

(A few days later)

John stood at the gate of his parents home, there was blood everywhere, same as every other home in the Compound. He was going to kill Danzō for this, he never hot the chance to use Kotoamatsukami on the Clan but fould still perhaps use it on Danzo. As he surveyed the scene he Saw his Sister's body was still there and that the ANBU Hadn't removed it or those of the other Uchiha Present. Taking this opportunity he Took the Sharingan from as many Bodies as he could get his hands on, he inteded to Transplant them into his Left Arm as well as to steal some of the First Hokage's Cells which would keep them in check, he also took their still barely beating hearts.

He cradled his Sister's body and carried it out to the ANBU before leaving to get the First Hokage's Cells. He would have his **** on Danzō, even if he had to die in the process.

(After taking the Hashirama Cells)

John had Operated on himself with help from his clones, he Transplanted Roughly Eighteen Sharingan into his left Arm, and followed it up with the Hashirama Cells he had Taken. Overall out of the Twenty five Vials containing The Cells he had Taken all but one. He planned to Use three vials for his Arm, and would Use two more on the Seal on his belly to stabilise whatever it held in check. He planned to use two more on the Back's of his neck he decided to use the Jutsu his Ancestors had created, the Earth Grudge Fear technique would require beating hearts so that he could stay Immortal.

Overall it was at first very painful and eventually the pain ebbed a bit. Now with the Earth Grudge Fear, numerous Sharingan, and the Eternal Mangekyō Sharingan he decided that if Danzō wasn't put on trial he would die.
