I loved Light's death in the manga. Ryuk writing his name because he can see that he's cornered, bleeding and lost, and because he doesn't want to wait for him to die in prison (much in character for him lol). I think his death was very well done. It was pathetic, but in a way that we got to see that not even Light is prepared to die, and is afraid. That behind that psycopathic mass murderer of a monster that was Kira... There was an actual human, scared of death, like everyone else.
I've only watched and rewatched the anime, and always found Light to be kind of a robot and a psychopath. But the manga made me actually feel pity for him. When you take everything that makes Light something akin to a God, you get a broken human being. I like it.
This one will definitely be ingrained in my memory forever.
