im having a debate with a friend,
in the final battle between vash and knives, does vash kill him or not?

No, knives is unconscious and vash carries him off

so how to you determine that hes unconscious and not dead?

because he defeated him with the power of friendship.
....wait, that was Soul Eater
nvm

need moar answerss

Do you really think Vash would kill someone?

Yet alone his brother?

He's a pacifist , that's all the proof you really need lol .

He disables Knives and then carries him back to town .

he kills that guy in the 2nd to last episode.
that shows he is willing to kill somebody in a dire situation

Well of course, that can be described as self preservation with the threats Legato was making against Livio

Still doesn't change the fact that he was a pacifist screaming love and peace for episodes on end .

unlike legato, if knives were to be disabled (all 4 limbs shot) he wouldn't be able to do any harm.
legato can still kill as long as he's conscious.
