Winston is being shot. He has finally come to the realization of his
love for Big Brother and has accepted everything and will be killed
now that his mind is cleared and he is "sane". O'Brien told him that
they never let allow anyone to leave without being fully "cured" and
Winston was finally "cured" of his insanity. In the beginning of the
1st of the last two paragraphs, Winston is coming to grasps that he
will be shot, but since he has wanted that bullet for so long, he does
not even dread his death or is scared. In the last paragraph, Winston
finally realizes his love of Oceania, O'Brien, Julia, and Big
Brother. Forty years of hatred toward the party and he finally has so
much love for them that he is satisfied with himself and therefore
O'Brien decides this is the correct time to get rid of him.
