Athena is the goddess of war and Wisdom, and the deuteragonist of the God of War series, mostly appearing as an ally of Kratos.
Of all the Gods on Mount Olympus in the God of War series, Athena is arguably the least selfish and is in fact, very noble. As displayed not only by her deep love for her people and her horror of Ares' siege on Athens but her deep concern and love for the rest of humanity - as in God of War III she states that she intends to "liberate" mankind with the power of hope.
Upon her death, however, Athena ceased to have these traits as she ascended to a higher realm and ended up being corrupted by the powers contained within said realm, and began to plot to take over the lower realm.
