What does Winston believe saves his humanity in 1984?Im stuck on this one! This question was asked on chapter three of book three. Thank you so...

His love for Julia. He believes that even though he has
utterly betrayed and renounced himself and everything he believes in, he has still held
on to his humanity because he never stopped loving her, even under torture. This makes
his final capitulation even more horrifying and symbolic. When O'Brien presents him with
the prospect of having his face eaten by rats (the thing he fears most), he "saves"
himself by screaming "Do it to Julia!" This illustrates the darkest, and perhaps most
ironic part of the novel: by saying these words Winston saves his physical life, but
O'Brien has succeeded in destroying everything in Winston that made him
human.
