Is Winston's obsession with big brother fundamentally similar to or different from his obsession with O'brien?

Winston's obsession with Big Brother is fundamentally different from his obsession with O'Brien. Big Brother represents the oppressive, omnipresent regime that controls and manipulates society, symbolizing fear and subjugation. In contrast, Winston's fixation on O'Brien is rooted in a desire for understanding and rebellion; he sees O'Brien as a potential ally and a figure of resistance against the Party. While Big Brother embodies the totalitarian power that stifles individuality, O'Brien represents a complex relationship that intertwines hope and betrayal.
