There's nothing to explain from God of War 1-2. Kratos was pissed off cause he's constantly abused. He was promised they'd get rid of his nightmares, and they didn't. He wanted to just end his life cause he was fed up with himself and what he did. Yet they didn't even let that happen. They forced him to be the new god of war instead. They didn't give him what he asked for, they instead did everything he didn't ask for. He became the god of war against his will, so he started wars alright, pissed off the gods good. This led to a paranoid Zues to get even more paranoid about Kratos killing him, since Kratos is his son (Zues killed his father before him for instance). That last sentence is the story for God of War 2. Whatever happened in Ghost of Sparta is either retconning things or just adding (Not sure which or both, since I haven't played it yet).
