Gaius's Intentions

[Magis]

As for Gaius' intentions? I do not believe he sought the Throne. If he did, he'd be back in Garlemald right now, jostling with all the other contenders.
I believe what he wants is to see a world unified, and led by man, free from the influence of religions and deities. A world led by the power of its own people and rulers, not blind faith. And if he can steer the world to achieve that, he will do everything he can.

I believe nothing pisses him off more than finding out that the Weapon he uses contains an Ascian god's relic and that the ascians themselves worship a god. You can feel the fury in his voice.
He wants a world free of primal influence and he believes Garlemald is the optimal utility to achieve that.

Hmm, kinda reminds me of FFVI. All magic was basically snuffed out, and the empire relied heavily on technology (Magitek).

It was actually kind of ironic watching Judge Vader get the ol' "I am altering the deal. Pray I don't alter it any further" treatment.

Yet even after Ultima is fired, he keeps fighting =\.

Truth to be told, if you were in his place and had the party trying to kill you in the meantime (I mean eight men on foot against goddamn tank, and they ARE handing you your ass, those guys ARE dangerous) I'm sure as hell you'd keep fighting.
He WAS given no choice there

I'm guessing that's about it. Yeah, you've just found out you've been used by something to do something you absolutely HATE. You've just been beaten around by 8 people with seemingly nothing that should be able to defeat you. They're likely extremely angry at you, so very unlikely that they'll let you go...

He's probably fighting as much for his own life as revenge or a need to prove something; these 8 just survived Ultima...they're nothing to laugh at, and have a VERY real chance to beat him. He may even just be fighting to try to take down one or two before he goes.
