As in everything else in this world, everything has it's good and evil purposes.
It depends on the reason a cloning will take, I believe. As long as it is used for medical purposes as to cure diseases and regenerate organs, there is absolutely nothing "evil" or "immoral" on it.
And I find quite ridicolous this over used expression so many people use "to play God", when cloning, as some others have already said, is nothing but make a genetical copy of a living being. Nothing else than that. Make a copy. There is not a creation taking place in the way "God" would do it, since there is basically no way of creating a human beign out of nothing, except from "copying" "it" from others.
But well, yeah, I really don't find a reasonable cause for cloning a whole human being, with a good purpose. To use them as soldiers, expendable figures in war?
blah, I began to talk bullshit now
