No. Not because of you. His life was death. He knew that.

You gave his life and death meaning. And that does mean something, to him and the world. You didn't kill him. Don't take the guilt away from his killer. It's not your guilt.

It's not all about you.

[He doesn't mean that in a cruel way, but as a statement. Evergreen's death is not Vash's fault. It's not wholly about Vash.]

He decided to leave. Yes, because you showed him something else. His choice. They killed him. Their choice.

Knives' sins aren't your fault, Vash.
