If it were me writing it, and this is purely a personal opinion, I'd go with something like:-
//We are here to form a world based on our views of life and each individuals importance and greatness. Our mission is to unite humanity and the world to harmony, which has been ripped from us by the megalomaniacs that rule us. We will help anonymously and with more dignity than the bravest warriors who fight for a power hungry leader.//
I think you then need a closing sentence but the one you had just didn't make much sense to me or scan nicely.
