What's wrong with Nadia? She gets raped by Simone and then chooses to stay with him. Is this an Italian honor thing?
Also, why doesn't she run for her life when he approaches her with a knife in the murder scene? Looks like she's embracing him with open arms until she gets stabbed to death.
It seemed like a cross between Stockholm Syndrome and Italian honor at first but when she leaves Simone for good she basically tells him that the only reason she had gone back to him after the rape was to permanently ruin him by means of draining him financially and mentally until he was broke and completely reliant on her to serve his emotional and sexual needs and thus entirely dysfunctional without her. I think her embracing of him during the stabbing was her willingly going along with her own murder because Simone had "ruined the only beautiful thing in her life", meaning her relationship with Rocco and had nothing left to live for so desired an end to her suffering through death.
shareI agree with Holy Shackles, and would add: after he stabs her, she is in tremendous pain (harrowingly portrayed!) and also she realizes she really does not want to die. Sort of echoes the scene where she is about to jump off the building and then looks down and decides on the spot not to do it.
shareyep, you explained it well
so many movies, so little time
