Throught the books Narcissa isn't really definded if she follows in the footsteps of Lucius and Muggle hating (or maybe i didn't notice)

in the 6th book she is more concerned with Draco's saftey than him compleating the task set, even though Bellatrix thinks she should allow her son to die if needs be.

what do you think Narcissa Malfoy is Mean or Nice?
