Maybe there's a video game where you can live out that fantasy.
Seriously though, all followers of Islam could disappear from the face of the Earth tomorrow, and very little would be lost in the process.
Genesis 9:6
Anyone who sheds the blood of a human being, by a human being shall that ones blood be shed; For in the image of God have human beings been made.
So that rules out the idea that about a billion followers of Islam are worthless and could "disappear from the face of the earth" with little loss.
Deluded they are in their false religion. But worthless they are not. You'll have to talk to God about that.
