it starts out as light (the main character) trys to find meaning to his life when he stumbles across a note book that can kill people. finding this hard to belive he tests it to find out its the real thing. he starts out with good morals but becomes power hungry and starts beliving he is GOD and that he should pass down judgment to all who oppose him
the writters of this anime show that those who have power will lust for more they will go until it is absolute the same goes for light who tries more and more to controll the world so in conclusion all those who have power will be corrupted
