It may be possible that Squaresoft where showing there opinon of religion. They also have based it on facts. As Monks in the middle ages took complete advantage of religion to boss people about, but let they betrey their own teachings just like Yevon. I mean one of the comandents is thou shall not kill. Yet before modem times it seemed alright to kill none christains. Like in the Bloody Crusedes. It's even in the Bible, where Joshua and his men broke down a city wall and kill innocent people. On what seemed like Gods orders. So Squaresoft are probally trying to say beware of relgion. They could exploit us. I think that had something to do with wakka being so trusting of yevon and hated the Albed but then found out that the albed was good and Yevon was bad. Yevon made people hate the Albed. Just like Monks made Christians in the middle ages hate non-Christains.
