he killed guy to get it
This is the most logical answer.All trolls aside, he suffered his loss of Obito and or Rin, the pain of which allowed him to unlock MS through training.
no one said he killed rin sum trolls said he killed Guy, i said he mighthavewitnessed rins death causing him to be able to unlock itPeople still think itachi was serious when he said you have to kill your bestfriend to get the MS. All it takes is training. When he saw Obito die he didnt even have the sharingan. and he did not kill Rin -_- All it takes is training.
Not just training, you need grief or guilt, hence the killing of the best friend. Madara and Izuna were shown doing it that way, even though they didn't seem to care much. That is why Sasuke didn't unlock his MS until he found out the truth about Itachi. Kakashi probably felt the grief of his friends passing away and blamed it on himself.People still think itachi was serious when he said you have to kill your bestfriend to get the MS.
