Owlman Destroys the Multiverse! (what a douche)

Theoretical physicists are always rambling on about the Multiverse these days. There's no real evidence for it, but they insist the math of their highly speculative, unproven and in some cases unfalsifiable Grand Unification Theories require their existence. Many of them apparently feel a need to destroy any gaps where God could hide. Although an infinite Multiverse would explain the apparent fine tuning of our Universe by sheer random chance, if there were an infinite number of universes where anything possible could happen, then in one of those universes God would come into existence. From there He would assume command of the entire Multiverse, doing away with the vast number of uninhabited and uninhabitable universes. Also, an article from new scientist called "Why physicists can't avoid a creation event" indicates that not even a multiverse can be infinitely old, so one could always choose to believe that God created the Multiverse.

I would like to add a logical argument against the existence of an infinite multiverse, which occurred to me just today, and was inspired by a cartoon super villain. A short while ago, I saw the animated movie Justice League: Crisis on Two Earths (Warning: Spoilers! ). In this movie, Owlman (Batman's evil counterpart, but not an alternate version of Bruce Wayne) attempts to destroy the Multiverse by detonating a doomsday device on Earth Prime (the first universe), which will have a cascade affect and destroy every other universe. I'll give you a quote to explain his motivation for doing this.

"Every decision we make is meaningless because somewhere, on a parallel Earth, we have already made the opposite choice. We're nothing. Less than nothing... I choose to make the only possible real choice."

By destroying the Multiverse, there can be no alternate universe where he did not destroy it. The only possible real choice, indeed.

What does this have to do with an actual Multiverse? Well, if there are an infinite number of universes where anything possible can happen, then in one of these universes there would be an entity capable of destroying it who shared Owlman's sentiment, and the Multiverse would have been destroyed. In all likelihood this entity would have been a post-singularity hyper-intelligence as opposed to a Batman knock-off, but it doesn't really matter. Since our Universe does exist, this obviously didn't happen.

This argument relies on the assumption that destroying the Multiverse is possible, even if it is almost infinitely improbable. In order to be a multiverse, all the different universes must be connected in some fashion, meaning that they could also influence each other. Some sort of cascade reaction causing the Multiverse to come apart at the seams should be possible. Tvtropes refers to this as a Class Z Apocalypse.

The threat of Owlman does not rule out the possibility of a multiverse, just an infinite one. The multiverse would have to be finite, and small enough to statistically prevent an entity both willing and able to destroy it from coming into being, or else we wouldn't be here.

So what say you, Brian Green? How does the infinite multiverse fare against the likes of Owlman?
