to me it seems like obito and kakashi are not trying to kill one another

if obito could stab his chest with the giant shuriken and slash him to make the x scar,
didnt he have a chance both times to slice his throat or stab through his heart.

kakashi with chakra replenished dosent use chidori while catching obito by surprise in the dimension.

there are more examples.. its kind of ruining it for me
when obito runs up and knees kakashi in the face in 608 im like really a knee, i thought you want him dead
if you have time to knee him stick a kunai through his throat

im just sayin
