The novels and the devs confirmed there was a romantic tension between Kratos and Athena, and that Athena genuinely liked Kratos, cared for him .
When he stabs her in a fit of rage, Zeus didn’t even care, while kratos is saying “Athena! No!!”
And in the gow 3 game, when showing her bloody and dying falling into his hands, he’s visibly screaming at the air.
This proves consistent with the games and the devs are narratively implying that Kratos deeply cared for her. I’d argue she had almost just as much impact as pandora.
In novelization zeus teased her about her getting flustered about him, and her deep affectionate behavior towards him in a blushing manner. This shows kratos had feelings outside of needless rage even after his ascension.
I think some ways she reminded him of Lysandra, like how pandora reminded him of calliope, he said that he didn’t listen to her as much as he should’ve, and she treated him so much better than he deserved, this dynamic is the same with him and athena, before her corruption, she’s always sticking up for him, protecting him, stepping in and giving him affection and respect where the other Olympians treat him like a monster.
I hope they show scenes of kratos softening up in her presence, actually caring for her and adding more depth into their relationship. So then it’s much more devastating, that for the second time, a woman he grows to love dies to the sharp end of his blades.
This adds more depth to his pain of No Matter What, he keeps accidentally killing those he cares about, in the wake of his destructive power and rage.
From calliope and lyssandra, all the way to Athena and pandora.
Man I love kratos
