Okay, I have to admit, I am a sucker for epic speeches followed by the bad guy getting the mother of all beatings. So I would like it if, in the final battle, Geed tells Belial (or whoever the final enemy is) that his human teammates will never quit as long as they live. But Geed? He has a different problem...as in, something like this.
What can I say? I'm a real sucker for one of the good guys giving a World of Cardboard Speech. It's just so awesome to see a hero, who has constantly been holding back, finally decide to cut loose and unleash his true power on a really strong enemy.
