I personally don't think it was Yu Yevon.
If you listen to the Fayth and the old scholar, you learn it was mostly Yunalesca who did everything and Yu Yevon himself devolved into a pure force with no good or evil. Just existing to summon Sin eternally.
So, I'd say the Yevon religion is the main antagonist. That or Seymour.
