Your objective is simple: Soul Accumulation

Your motive is a little bit more complex: Sadistic pleasure

Stage One:

To begin your plan, you must first Assassinate a Pope. This will cause the world to sit up and take notice, stunned by your arrival. Who is this Despoiler of all that is Good and Nice and True? Where did they come from? And why do they look so good as an Evil twin/Opposite?

Stage Two:

Next, you will Desecrate New York. This will cause countless hordes of Computer Programmers to flock to you, begging to do your every bidding. Your name will become synonymous with Dear God No, as lesser men whisper your name in terror.

Stage Three:

Finally, you will Covertly Move your Needlessly Big Weather Machine, bringing about the Apocalypse. This will all be done from a Dark Side of the Moon, an excellent choice if we might say. These three deeds will herald the end, and the citizens of this planet will have no choice but to elect you their new god.
