The death note

[srh]

peace be upon you all
i hope you are fine................an' i hope you'll enjoy my topic........okey ...well i start............i've seen a monga that is abou a prodigy named Light, who happens to come across a notebook, that is owned by a Shinigami (death god) named Ryuk. This notebook, has a mysterious power. When you write a human's name in it, within 40 seconds they will die. You can choose to tell how they die, or if you leave it blank, they will die of a heart attack. Thus Light who has become disgusted of the world, decides to change it for the better. He starts a campaign to rid the world of crime. But what sacrifices will Light give to obtain his new world?
so if you were instead of light what would you do with this DEATH NOTE................EXPRESS
