Explain the dark meaning and implications of winston Smith's final words: "He loved Big Brother......"

I would think that there can be many approaches to taking
this particular phrase and its meaning in the work.  The idea of Smith's "love" towards
Big Brother is quite the opposite.  It simply means that he has stopped resisting the
government.  Throughout the novel, Smith's development as a character has emerged
through his desire for freedom and acting against the authority structure.  Yet, with
his brainwashing, this part of him has died.  In the end, his "love" for Big Brother is
actually quite the opposite.  Love would imply complexity and intensity of emotion. 
Rather, this "love" is simply acquiescence.  He no longer lives his duality of resisting
the party as this has been overcome and with this overcoming, "love" results.  In the
end, this contains dark and sinister overtones because so long as surrender is evident,
individuals can be deemed as possessing "love" towards the
government.
