I mean to say that Cloud cut Sephiroth mostly in half, and that blow killed Sephiroth.
imo Sephiroth is kind of dying even as he tries to leave the reactor. Being hurled from a catwalk into a wall, then falling 100 metres into a pool of radioactive waste sounds to me like it would finish the job the Buster sword started.
Oh! I missed this:
I disagree. Hojo immediately gives up actual science as soon as he's able to claim that his son is awesome, because Hojo's flaw is Pride (well... his
fatal flaw) In fact, Hojo's immediate and untested assumption that Sephiroth (and not the head or the Lifestream-saturated rendezvous point) is what drew the flunkies is a result of his hubris and narcissism, not scientific thought.
Thus it has thrown the Jenova vs. Sephiroth debate into pure anarchic chaos.
