Wouldn't kill for the sake of their goals?

[for love? or to be reunited with the ones they'd like to see? buzen looks thoughtful for a moment before smiling sheepishly]

... I only have my reason, but admittedly it's different because I'm a sword who was forged by humans.

When the other people I want to see are also swords... I think they'd be pretty disappointed in me if I came back, killing people to return to them. They'd feel... guilty, I think.
