JKR has taken great care in naming her characters, and Narcissa is no exception. Her name comes from "narcissism" which means (in a nutshell) selfishness and a craving for admiration. Narcissa is focused on what is most beneficial for her (and the people she cares about). I don't think she was really trying to help the "good side," so much as just saving her own family. Andromeda's decision rather than inspiring her, would probably turn her the opposite way. She saw how Andromeda was shunned and disowned, and felt it was better for herself to carry on with the rest of her family. Narcissa comes from a line of witches and wizards who all have the so-called "blood-mania." I think she joined up with Voldemort for the same reasons Draco and his fellow Slytherins did: family pressures. It's doubtful that she actually knew what she was getting into in the beginning. Later on I'm sure she realized what was actually going on, but again saw it best to stay, if only to save her own skin. You can't cross the Dark Lord and come out unscathed (ex. Regulus Black).
I completely agree. Once her son and her husband were in danger, she couldn't sit back on the sidelines. Narcissa was never as loyal to Voldemort as she appeared. She did not act to help the "good side." She has the spirit of a Slytherin; she is loyal to only herself and her own.Originally Posted by untitlednine
In a way I see her as the Slytherin Molly Weasley. She won't be in the thick of things in general, but lay a finger on her family and IT'S ON!
