Even for those standards.. It's purely asinine.U dont even know how Madara, Izuna and Itachi mastered their Sharingan.
Maybe it was just one day and they all had 3 T, maybe it was years, maybe they were born with it o_o. But one is sure. We dont know.
It was said they mastered the Sharingan young, and they didn't get the Mangekyou until their late teens. Still no.... & don't you think it's unfair to give that kinda of power to a fodder ninja when a genius like Sasuke didn't master his until he turned 13, the trauma activated his first tomoe at 7.
