It's all opinion, I guess, but the way the story reads I agree with most points in that theory I posted.

*SPOILERS AGAIN*

Jenova was behind the scenes. Sephiroth had no real power as you can see from the ending when Cloud just ripped him a new one when Sephiroth no longer had Jenova helping him.

Cloud and Sephiroth were "puppets" of Jenova. One thing would be like in the beginning when you are about to destroy that Mako Reactor and all the sudden Cloud raises in the air as to imitate a puppet. Then writing comes on the screen telling him are you really sure you want to do this? or something to that effect. That is Jenova. All the wierd voices, Jenova.

Sephiroth really was just a figurehead.

The whole time Cloud was fighting against Jenova overcontrolling him (all the wierd Cloud mental breakdowns). Sephiroth just gave into it. Which made him quite the badass but at the end, destroyed him.
