Answer:
The final lines of the poem rightly reassert the importance of community and how no man can be left alone to survive on his own, away from other humans.
Explanation:
In his poem "No Man is an Island", metaphysical poet John Donne talks of the importance of a community/ social interaction for humans to be sane and civilized. No man living alone and away from other humans can survive on his own, irrespective of what may have been presumed.
The lines 8-9 of the poem reads <em>"And therefore never send to know for whom the bell tolls; it tolls for thee"</em><em>,</em> which perfectly presents his point home by generalizing the death toll that is ringing for anyone. It could be for you or for me, but that's the uncertainty of life, for we know not when we will all die, but we will die one day, that is a certain fact. Being part of a society or among people is needed for a man to thrive and survive. And one day, the bells will toll for thee. These final lines perfectly resonate the important theme of how man is a social being, and not to be left alone/ living alone. These two lines reassert the importance of man's social dependency on others, his inability to be self sufficient and his need to be in the company of others.
What makes them similar is that that both Charrington and O'Brien seem to be on Winston's side, i.e. against the Party. Another similarity is that they both end up betraying him, essentially they deceived him by hiding their true intentions from him. Charrington uses a literal disguise, while O'Brien was just pretending to be something he is not.
