I think the climactic moment is when Bond finds a way out of the burning inferno, instead of shooting Camille. That single moment represents when Bond is able to pull back completely from the edge of going completely insane from the burden of Vesper's death. Prior to that moment in the movie, he was basically a primal killing machine, his desire for revenge and his thirst to satisfy his guilt overwhelming his judgment and his thinking. Even when he admits sympathy for Fields' death to M, I think he's still contemplating killing Greene when he gets the chance.
Camille serves as his redemption, so to speak. The one he saves for the ones that die. The way he's able to preserve life from the jaws of death.
And that's when he becomes the James Bond we're used to.
