Really? I mean, I mostly hate billionaires.

Wait, how many people can a single ghost take out over the course of its existence? Can a billionaire ghost take out more people than one who died below the poverty level? How long is a ghost’s existence? Is it unable to move on because it hasn’t yet eradicated everyone it wants to? What if it is just unable to for whatever reason? Does it simply roam the Earth forever harming other people that it didn’t even intend to originally?
