>>714283384I don't think that was what they were going for. Correct me if I'm wrong but the problem wasn't just Pyra wanting to die, the problem was Pyra wanting to give up. The destruction of Torna ruined her and Pyra was just as hopeless as Malos, Amalthus, and Klaus was. Unlike Malos who decided to have fun watching the world burn, Pyra moreso gave up on herself and just wanted to die. Because do you justify so much blood on your hands? So yeah, in that instance Rex needed to carry that weight so that that Pyra, and Mythra, could live again.
In the ending it wasn't about giving up anymore. Pneuma knew she had to stay behind to keep Megaman X5 from being canon. Yes Pneuma believed she was going to die. But in this instance she's trading her life to save the world, not blowing it up with her Gundam mech suit. As she tells Rex, she loves this world now. And everyone understood that. Hell I'm sure Rex understood it but he was never going to accept it because by then he'd resolved to carry Pneuma's load for her. And seeing as how Pneuma loves Rex, she'd never allow him to join her death march.
