What? No, that's not right. Shinigami's can/do kill people before they are meant to die. That's how they extend their own lifespan. They are meant to die if they kill someone that is going to kill someone else, and if they has knowledge of it and did it to save that person. That is why Gelous Died when he saved Misa. Rem died when she killed L because L was going to inadvertently kill Misa. It was Light's plan for Rem to think that and completely disregard that she would be saving Him aswell.
