I think you're forgetting how he was convinced by Athena that if he killed Ares, he would be forgiven for his crimes. And the fact that he mis-interpreted what she said to him. The entire narrative thrust of the first game is him going to kill a god, at the behest of another god, with the intent to be forgiven. Which isn't what happens. He realizes at the end, that he can't be forgiven, and so he decides to kill himself by jumping off a cliff. But the gods, deny him his choice of an ending, and literally yank him up to Olympus, and force him to become the God of War. Athena even says something along the lines of "I told you X, I never said you would get Y"Casual Shinji said:I'm not an expert on the subject, but my understanding of a Greek tragedy is that it's supposed to show how mortal men are but playthings for the gods, and that if one of the gods sets their sights on you you're a slave to their will. And to me Kratos never felt like his hand was being guided by anyone other than himself. His "tragedy" is suppposed to sort of reflect that of Hercules who also murdered his family, but he was driven mad by Hera. So his actions where beyond his control due to the malevolence of a god.
If that's not an example of "plaything of the gods", then I don't know what is. xD
I'm personally very optimistic of this new GoW game, because I'm pretty sure that what we are seeing is the creation of the Norse pantheon, with Kratos becoming Odin, and the little boy being Thor. And the "Ready for what's coming" is Ragnarok, something that Kratos unleashed when he couch fucked the Greek world in GoW 3.
