The reason why kakashi killed rin.

[uchihamad]

I have got some clues about why kakashi killed Rin.

My clues are

1.All of the mist ninja that surrounded Rin and Kakashi were wearing Mask.It meant that they were Mist hunter ninja.

2.So Mist's hunter ninja were after Rin because her body contain valuable information about kirigakure ( May be Rin is a spy from kirigakure.) So they wanted to erase the details by completely disposal of her body.

3. Kakashi knew what was going on so in order to not get any information about Konoha he killed rin.

She couldn't be a spy, she was buried in konoha.

I only said may be

but mist hunter nins dispose of bodies. Why kill someone marked to die?

 

[Punk Hazard]

She was buried in Konoha. A spy couldn't have been buried in Konoha.

Anyways, one of the Mist ninja mentioned experimental bodies. I believe they experimented on Rin and Kakashi needed to kill her since she was now a liability to Konoha.

 

[Machiko]

Unlikely, Kakashi would never kill a comrade and even more so since Obito made him promise to take care of her. What could've happened though is that Kakashi may have been in some sort of control ninjutsu (like Ino's mind transfer).

 

[karol the don]

mbe they wanted some informations from her and the only way that they dont get it was slayin her down

 

[BazzBee]

very true awesome theory

 

[ObiFan]

Other reasons I thought about are:
A) Kakashi swore to Obito that he would protect Rin,and because they were in danger,he decided to save her by killing her.

(Version B is never gonna happen btw)

B) He killed Rin,so he could obtain the MS,even though that is gonna happen by a long shot.

C) Obito was probably put over a genjutsu.

And with this saying from Madara,it looks like C might be true.

i dont think she got that some kind of information, it might be that kakashi thought they would die so he killed rin rather she got killed and suffer(why for the fact that when he stab rin with raikiri he pass out, meaning he doesnt have chakra for fighting those mist ninja to protect rin, so maybe he knows that he will get kille and rin -of course- would get gang banged before they kill her so he killed it before that happen).. if so it's not kakashi's fault it's minato. for being not there again..

That's not Minato's fault...

 

[Lawliet L]

That's not Minato's fault...

ok why did obito died at the first place? did kakashi left his teamates before? if so, they have a back up. so it's minato's fault for being not there again for the 2nd time.. (he didnt learn from his mistake when obito died) like what if your sister died from an accident and u still has a little sister you will let that happen again?

 

[roncato]

I think genjutsu was cast on him.

 

[xjimbox]

She couldn't be a spy, she was buried in konoha.

Maybe it was a secret mission and didn't want to tarnish her family name

 

[Tec]

She couldn't be a spy, she was buried in konoha.

Wrong. Obito took her body.

because the mist made kakashi confuse that rin was an enemy

Minato isn't a babysitter. The first time he wasn't there is because he had to help stop a WAR and protect OTHER people. Those 3 had a simple job - destroy a bridge. Minato wouldn't have been able to fathom their uselessness. If they need minato to babysit them then they don't deserve to live. Your arguement is moot

 

[lytie]

I think Madara was behind it all, he said to Obito not to go looking for his friends and then all of a sudden Zetsu helps him?

A bit fishy dont you guys think?

Madara knew that would be the only way to get obito to join him...

 

[Noni]

She couldn't be a spy, she was buried in konoha.

they probably just buried her there for respect because she seemed to be a konoha villager for so long...
that they still respected her enough to give a proper burial
