Do you think Kakashi actually cold blooded killed Rin? Do You think Rin Was a spy? Was it a set up by madara? Was it genjutsu?
I have a Few theories.
1. Kakashi was the spy and Rin found out so Kakashi killed her. (I personally believe this one)
2. Rin Was the spy
3. It was Madara's genjutsu. Because he can create any illsuion he wants in his genjutsu.
Just had some random thoughts
