Nigga they say, FROM THE OUTSET that you have the power to bring them back, the point of their sacrifices isn't to give you a death rugpull, its supposed to be symbolic of humanity as a concept, how every victory, every road, every push forward, cost human lives, every acheivement, everything we've ever accomplished was built on the backs of millions of people, and now its down to your 7 best friends all making their claims against entropy, despair, and hoplessness.
none of them are more clear than G'raha's little speech to the Robot Omega race being.
there's a reason each being they oppose are their mirror opposite or have something thematically tied to them, Esteninan to conflict with another Race and what that brings, Urianger and Y'shtola with the pursuit of knowledge being told by a doomsaying race that everything has already been learned and its fucked.. G'raha Tia with existentialism over what it means to be alive/yourself, ect.
