The way i see it, and someone else might have gone there, the first game kind of kept Kratos sane. He had a goal. Hope was there for a future without the memories of his past. But when he found out he was being lied to again, he snapped. True psychosis would envelope him. He would become pointlessly brutal because he doesn't care. He has no hope. He has seen the abyss and is going to throw as many things into it as he can since he no longer can. When Zeus attacks him, he finds goal. He has purpose again. Remember that whole "Death cannot hold one with Purpose thing" athena said. That's why he could escape. Gaia presented herself and offered redemption to him... again. But now he's not holding back. He feels he's all but lost the capacity for redemption. He's going to end everything. But when he finds Pandora, a bit of humanity shines through. He remembers his daughter. He begins to feel as if maybe everything he's doing is really the best way. Remember that before he found he, Kratos was willing to throw Pandora into the flame himself. But he tries to stop her, but must make the necisary sacrifice. The last of his rage is let out on Zeus at the very end. He's completed his quest, he has been shown that he can be redeemed, he simply must forgive himself. When he does, he realizes the full impact of his actions. Knowing he can't live with himself, or the possibility that Athena would take over, enacting a new Olympus basically, he desides the only course of action is to give mankind what he has deprived them of, the hope to live on. Without it, Athena cannot control them. With it, mankind will find a way to survive. They will look to the future.
That's very over thought, and probably not the writers intentions, but I like the idea. It seems a very strong Greek tragedy to me.
