If you ask me, you're doing the right thing. If there's a chance to save everyone, you should always take it. Sacrificing others is never acceptable... even if you're up against an entire army, I think you'll win. Heh, that's how it'd work in manga anyway.. but even if you don't manage to pull it off, I still think you're definitely doing the right thing.

But I guess you already know that, or you wouldn't be doing it.
