ryuk nvr betray light since shinigami is not suppose to fall in
love wif human.
correct me if i'm wrong, Rem died (turned into dust) becos he wrote
L n his bodyguard's name so dat Misa would not fall into trap of
shorten another half of her lifespan for another shinigami
eyes.
alot of viewers might have doubt why ryuk not dead since he wrote
the name of Light n turned to dust. is it becos Light is dat owner
of Ryuk's Deathnote thus Ryuk has right to kill him n hence still
survive?
