What would tu do if tu owned a Death Note?

Write down a lista of my enemies, then how I want them to die.....Simple.

I would write the names of any murderers at large to stop them from killing anymore. And to make it all fair, they die how they kill.

First, make sure there's no extremely intelligent detective that I'd never be able to beat hidden somewhere in the world, especially if he's named L.

If there's not?
Become an anti-hero and rule the world.

If there is?
Laugh like a maniac and burn it.

Not use it until I really needed it. I'd probably bring it with me everywhere though just in case.

Everything. I'd RULE the world!!!

Mwahahahaha!!!

Kill all the people who are not enlightened to the power and goodness of Satan.

Kill Kony, Kim Jong Un, All members of Isis, whatever remains of Al Qaeda, the Neo Nazis, and the KKK. Then I will burn the book and throw the ashes in the ocean.
