This had to be the most raw moment in the series because the fact that she was like “My baby is okay that’s all that matters, and I know what will happen if Voldemort wins, so let’s end this.”
I mean, Voldemort lost because he trusted his followers to be implicit in their loyalty, but a lot had changed in the decade since he’d last terrorized the world. Like…the Death Eaters for the most part were calmed down and writing off those dark days as the “wild days of their youth” and shit, so when Voldemort pops back up ready to pick up where he left off, you could see a lot of the doubt in them like “Yo we grew up, son, shit ain’t like it was before.” But they followed out of fear mostly, not loyalty. Bellatrix was just crazy and in love with V so it didn’t matter to her what happened—and it ultimately led to her death.
But Narcissa was raw as fuck because she knew SOMEBODY had to stop him and she knew her husband was too scared to do it himself, so she devised her own on-the-fly plan.
The HP series is way too dope to be written off, and most of the detractors who write it off are just jealous of the hype it gets, but if you really read it, so many themes are covered in the story, chief among them being growing up and the expectations therein.
…am I rambling. I need to stop.
