I'm not exactly sure what you're speaking of... you learned there was a way to bring back the dead in school? Did you mean 'legend' when you said 'legent'? Not to rain on your parade, but it's highly doubtful such a thing exists. I mean, I guess it could be possible, but you should know that the chances of finding a way to resurrect someone is very very very slim. Sorry if I understood you wrong, but that's what it sounds like you're talking about...

As for what is worth fighting for, I'd say anything you believe in. Friends, family, ideals, life, etc, etc, etc.
