Yeah I did, but that doesn't change what I said. He better have a good explanation.
I can see Rin asking him to do it because she's trying to be all Ninja and suspects that she'll fall into the enemies hands, and doesn't want to leak any information... but that would be stupid imo. If Kakashi did this on his own initiative because he feared that she would be captured... then I will hate him.
Basically if this is in any way Kakashi's fault, whether it is due to negligence or some kind of miscalculation he made, I'll be a little peeved. But if the circumstances they're currently in are not the result of bad decisions that Kakashi might have made; and their luck just ran out, I might be able to understand.
It's also possible she was under genjutsu and they made her make threatening moves towards Kakashi, and his reflexes took over or something. Although that would be stupid as well.
