Greed and evil don't have to make sense. They just motivate people in power to serve themselves at the total expense of all others. They do not care about consequences. They do not care about the future. Which is interesting, since they all think they'll live forever. But absolute greed and evil means living for the moment, consuming everything, even that which is not needed or wanted, and leaving a wasteland behind.
Sense? Why even bother with that word?
