Okay, I am sure somebody else somewhere has thought of this, but I was just watching the ending in an LP and had a bunch of thoughts and it all sort of came together like this.
Sephiroth wants to never die. He’s also ferociously lonely and has a horror-hunger-level need to belong somewhere, while simultaneously knowing in his gut that he does not, cannot belong with 99.99% of people on the planet. Back at Nibelheim, he found out the surface-level stuff about Jenova and lost his shit, assuming it was accurate that she was an Ancient and probably getting some influence from her. So during his first meltdown--he believed he was an artificially created Ancient, and wanted to kill all the humans and take the planet back for the ancients. Again, he was probably being manipulated by Jenova at this time, but it’s unclear how much that could influence his emotions and behavior. Then he was thrown into the Lifestream, where he undoubtedly learned the full truth of his own creation. He then supplants Jenova’s will, because she barely has one and he is a person with feelings, and turns all her powers towards his new goal of smash meteor into planet and become god. I’ll have to recheck dialogue, but if I’m not mistaken he doesn’t actually want to completely destroy the whole planet. His intention is to kill every living thing on the planet, absorb all the lifestream, and… make a new planet? Use the power to travel through space like jenova? Idk. I like the former for my theory, because then I can conclude he assumes he would of course belong to a new world of his own creation that he reigns over like a god. But I can’t remember how thoroughly he described what he wanted to do after Meteor.
So. He’s prevented from completing that goal by the events of the OG/compilation, but he cannot fully be killed either and just hangs out isolated in the lifestream until the Planet dies, much later. Sephiroth cannot have the actual planet actually dying. That makes him die too. So he uses a mix of Jenova and Lifestream powers to go back in time. He can’t change history himself, that’s part of the planet and he isn’t, and for the same reason he can’t really affect the whispers, although he can stir them up. So he has to use his influence over Cloud and other Sephiroth clones to achieve his current goal of never dying. And he genuinely believes that his interests and Cloud’s interests align for this. Why, Sephiroth is actually trying to save the planet! That’s what Cloud does! ...not to mention that throughout his entire life, Cloud as the sole successful Sephiroth clone is the closest thing Sephiroth feels he has to a peer in the entire history of the planet. I am not familiar with Genesis and Angeal, but for the sake of this theory I have to assume that Sephiroth preferred to dismiss them as clearly inferior for dying rather than feel any grief or closeness or anything. He has come to respect Cloud because Cloud’s the only one who has repeatedly been able to defeat him. Therefore, I think he’s being as sincere as he can when he’s talking to Cloud throughout Remake. Manipulative, yes. Not telling him everything, of course. But if there’s one thing I have noticed about Sephiroth’s character over the course of 25 years of playing the OG, it’s that he is not actually particularly interested in outright lying. The main time he is believed to be lying, it’s unclear whether he even realized at that point that Cloud was the same soldier that was at Nibelheim, and if he did he might not have realized how much of Cloud’s persona was still him and not just a weird Jenova-crafted show. I think the Zack stuff is very likely things Sephiroth is attempting to offer Cloud, or things Cloud subconsciously changed without fully realizing what he was doing.
Anyway, the main reason I really like this whole theory is that a. This places Sephiroth and his worldview in direct opposition to Aerith. Aerith is connected to the Planet and must accept the inevitability of her own death as well as the Planet’s. Sephiroth is isolated from the Planet and refuses to accept any such thing. Which I feel could lead to some very interesting push and pull on Cloud, as Sephiroth could very well attempt to push Cloud to save Aerith, trying to get Cloud in a headspace of refusing to accept death, while Aerith would insist on letting go for the greater good and the natural order. (Not that Sephiroth will in any way try to avoid killing her. He can’t change the past, and the point isn’t “let Aerith live”, the point is “make Cloud change things to save her, make Cloud change things to save everything forever including me”). And b. it does as much fleshing out of Sephiroth and his development and motives as the Remake has done for every other character so far. In my opinion, Sephiroth is not and should not be portrayed as a flat evil villain. He’s cold, disconnected, cruel, and inhuman, but in a lot of ways he is still very human. I have felt for ages that it was Sephiroth’s very human emotions that made his will strong enough to completely supplant Jenova’s will in her own cells, and his freak out in Nibelheim was a very human reaction acted out with terrifyingly inhuman strength.
...anyway that’s just where I’m at with Remake Sephiroth right now. My opinion will probably change again next time I play through, and I will probably be wrong no matter how much I like any of my own theories, but I’m enjoying the ride. It’ll be fun to test this theory again the actual remake dialogue and see if it holds up.
(Sephiroth, I accept I am very likely wrong about. Certain other characters? My god I hope I’m right about Reeve, I will be so disappointed if my remake-inspired rethinking him through is too far off the mark.)
