What sort of philosophy is that? To give up your entire existence just to let some friends of yours go back to where they came from? What would happen to them if they stayed here? They wouldn't cease to exist, would they? Of course they wouldn't. They might get a bit homesick, and that's about all - a mild irritation in comparison.

Even though things went as well as they possibly could have, thinking like that isn't fair - not to yourself, and not to anyone else. Genuine friends wouldn't want to risk trading their friend's existence for their own convenience. I would have died, and you would've stopped existing, which is probably the same thing as dying, and look at us! We're both young, we're both supposed to have entire lives ahead of us, futures to look forward to!

So why, just why would you even for one moment consider sacrificing yourself like that?
