Remove some of Varus's voice lines that make no sense anymore

Maybe he really does have nothing to lose.

He (they..?) already lost his old lore after all :^)

He's getting a new VO along with MF

Still fits though, coming from new "Varus" the darkin bow. The rest of his kind were wiped out, aside from the half dozen or so we either have or have been mentioned loosely. So he's out to wreck everything in the world in return.
