Should you go about ending the world, how would you do it?
First, I will come round your house and murder you. That should give some distraction. Then, I will visit the whitehouse and just teleport around until I reach the prime ministers office (I can teleport, I thought you should know, also I know where you live). Once I have done that I will implant a nuclear weapon inside his torso and make him invite all the world leaders to a party. Once they are there I will detonate the device and thus the world will go into a state of misery as they have no leaders. I would step in as a corrupted leader and therefore take control of all the nuclear weapon stations around the world. I would position said weapons in certain places and detonate them simultaneously. The world would be destroyed and I will be floating away in a spaceship towards the Deathstar (Did I mention I made the Deathstar?).
