I feel, how to unlock the mangekyou sharingan, is by seeing your closest friend die in battle,so the people who possesses the sharingan; truly don't need to kill their own closest friends, because that's what happened to kakashi, it's like Gohan using the "pain of loss" __
it's like the sharingan has a trigger or an amount of images to be seen until the eyes "cry".
cause crying releases "sadness and sorrow".
