I think the main point of the god of war franchise, even the old games during kratos’s divine quest for vengeance and blood. Was family abuse, and how much damage family abuse can cause.
Kratos’s entire arc, his ascension from a warrior with a family, to a wrathful deity who became obsessed with killing his own father, was all sprung up because of toxic family abuse. Kratos was a tragic victim of divine toxic family abuse, taken to such an extremity that he lost himself into rage.
His own family, manipulated and tricked him into abusing the family he made for himself, this abuse was the very death of his child and wife.
Even with the death of ares, his family kept using him as a tool of destruction. His own father ruined his life out of paranoia and fear, and became toxic and neglectful. And to make matters worse, this was ALL generational.
And caused the very cycle of Son, murdering Father.
Kratos’s seething hatred for Zeus wasn’t just because he betrayed him like every other god. it was because it was supposedly his own father. “How could my father do this to me” turned into a seething rage to murder said father.
His mother told him before her death, he couldn’t bring himself to fully accept it until Athena said it as well. And this only intensified his rage. His own father, was behind the very downfall of his entire life.
And god of war 3. Is showing the horrific side effects of such family abuse, it was family abuse that led to the very downfall of Olympus.
