When Winston and Julia pledge to carry out terrible orders from the brotherhood they do not?

Winston and Julia's pledge to carry out terrible orders from the Brotherhood reflects their rebellion against the oppressive regime of Big Brother, but they do not genuinely intend to follow through with violent actions. Their commitment is more about expressing their defiance and solidarity against the Party rather than a serious endorsement of its moral decay. Ultimately, their relationship and desire for personal freedom are prioritized over any violent allegiance, highlighting the complexities of resistance in a totalitarian society.
