My plan is to make a stamp that says "________ is killed in a global communist uprising on (date)". Set the date for about a year after I start writing down names, and every day fill in an entire page with the names of wealthy ghouls. I figure the Death Note can take limited control over people in order to make its designs reality, so if you get enough people killing the rich in the name of communism then cognitive dissonance will do the rest, making hundreds of millions of people worldwide into true believers in the revolution.
