-to remind Danzo of how strong he is
so he tortured an innocent man just doing his job for that huh...
-to intimidate them so he could run without being followed
for all they know at the time, kakashi had collapsed somehow. so how is that derreing them? and wrong. itachi is strong enough that he and kisame could escape without ever even touching kakashi and them
-Kakashi and Kisame would have gotten suspicious if Itachi was blatantly holding back
let them. they would stil have no proof and kisame wouldnt give a shit even if itachi explained everything. all kisame cares about is the jins and following obitos orders. how can you debate about itachi and not know the first thing abiout these people?
if anything kakashi figuring out about itachi is a good thing since then they could properly have a workable spy instead of itachi doing nothing for 8 years.
-Kakashi was holding his own without ms, more ninjas could have arrived
all the more reason to avoid any fights and just kill them. kiling them is faster and more merciful and it was what itachi ordered kisame to do anyway. itachi could have skipped the torture and gone right to knocking them out or escaping.
He killed his own clan, you think he cared more about Kakashi's well-being than his plans with Sasuke and the secret of his past ?
he brutally tortured kakashi for no reason at all except for fun and to see kakashi in pain
Itachi didn't kill kakashi when he had the chance, he had no killing intent.
itachi is an insane bloold hungru psychopathic monster. so yes he had killing ntent. iwth no remorse or hesitation he ordered the murders of 3 innocent people in cold blood at kisames hands for no reason at all other than to see some blood flow. itachi deserved every ounce of pain
