In the movie "The Ring" (2002), why does Aidan say that Rachel wasn't supposed to help Samara? And if Rachel had helped Samara, then why is she still killing people? And why does making a copy of the tape and showing it to someone else, free the person from the curse?
Recall that Samara is murdered by her adoptive mother because the girl had a malignant spirit. Remember the scene of the horses in the cursed video? It is explained that the horses threw themselves off the cliff because Samara frightened them or forced them to do it. In itself, the girl's body was only a vessel for the evil spirit and to die she did nothing but free herself. Rachel buries her corpse so she can rest but her soul is not good and now she can spread the world. If we go to the book (which doesn't look like the movie but can serve) Sadako has a very powerful mind that transcends time and can materialize but his soul is corrupted and only seeks evil.
In short, Samara was never good or a normal girl. Think about the last movie (very bad, by the way) where they explain the origin of Samara and who were hes parents.
The answer to all of these questions is that Samara is kind of a jerk. Admittedly, with reason!
Aiden says Rachel isn't supposed to help Samara, because while Rachel thinks helping her will put her to rest, Aiden knows that Samara is a truly malevolent spirit, who isn't interested in being put to rest. She just wants more chaos.
I'm not sure the technical reason (haha) why making a copy of the tape would free the person from the curse, but Samara's reason was that by doing so, more people would learn of her plight.
And just because they won't die in a week doesn't mean they won't be haunted for the rest of their lives.
Sorry to bring back this old thread, but I have a more logical answer to why she keeps killing. She was mistreated as we learned in the movie, so Rachel helped her as we also learned. At the end of the movie we pan into the copy of the video cassette and I imagine some people confused at this point.
The reason they panned in to the cassette is because she had just realized that because she made the cassette, the girl was happy with her. The only way you escape death and watch the cassette is by making a copy. Samara wants her story to be told, so when Rachel made the copy, she was happy.
At the end of the movie, it showed Rachel and her son watching it and making a copy, and her telling her son it's going to be okay. Samara keeps killing if the person that watches the tape doesn't make a copy. She wants her story to be told.
I hope I helped shine some light on the question, and wish you happy scary movies!
