As others have already pointed out, cloning organs will be a huge benefit to all of us in the future. We will also be using animal clones to repopulate extinct species in the near future.
As with anything humans get their hands on, cloning as a technology can be used in amoral ways, I would imagine that we will sooner or later see some rich person cloning himself for the wrong reasons, or people treating clones as less then human. But these things will be anomalies that will be addressed when they happen and corrected by laws enacted to curb abuse the same way we enact laws to curb abuse with any technology.
Failing to see benefits to cloning is a failure of your imagination, not the technology itself.
