Ms is unlocked by killing only

[celarian]

On the wiki it says that ms is unlocked by a traumatic experience, yet the only chance that is true is through obito, who I think got it not because he experienced it but because their eyes are linked, izuna and madara, got it by killing of there relatives on purpose, is would not traumatize them, itachi got it from killing shuishi, seeing he can kill his entire clan, I doubt it was traumatizing for an anbu level nin. And sasuke, kills itachi, also traumatizing but I doesn't explain why he did not get it when he was a kid during deep uchiha incident.

This is my theory, what do you think.

Thats why uchiha is on the extinct list, because they like to kill each other.

Yes strong emotion mainly stress basically

[KonanAkatsuki]

True

[Itachi2020]

I don't think killing is mandatory, traumatic experience is enough, as Sasuke didn't kill Itachi, but he got it.

[tamikasy]

how do u know madara and izuna were not traumatized?

[★Yáng..]

just thought i should point out that shishu didnt kill himself danzo snatched his right eye and took it he took out his left gave it to itachi and suicided ^^

[Kages]

Maybe.

[★Yáng..]

i should also hint out the ms is activated by killing or witnessing the death of your closest friend according to itachi and when the uchiha massacre occurred it triggered sasuke to awaken his 1t sharigan ^^ and obito well obito he actually saw kakashi's hand through rins chest which was his closest friend one of them anyways and he loved her her death triggered his ms to awaken same happened to kakashi

It was traumatizing for Itachi. He really loved his parents. It was a struggle for him to kill them. And he even cried right before he left.

You basically have to feel a traumatic experience of losin someone close to you. So by killin someone you like or seein someone close to you die

Itachi did not kill shisui
Madara and Izuna did not kill any relatives
