Should cloning be banned?

Cloning is a process which needs really careful treatment. If it is real soon, it could bring a lot of unnecessary and even dangerous consequences. But also, I am sure, it will become very useful in the future. So... should it be banned?

I suppose that cloning could make the lifes of people who have some scary illnesses. We could change our old or sick organs to healthy ones. And tell me, which of you, in your early childhood, have never wished you could have a clone of yourself to do homework while you hit the skate park or went out with your friends. Cloning could save a lot of our time and strength. But in the other hand if our clons are soon avalible to use people will become much lasier and less active. People will be taught only to consume and take, but not to give away. And it could happen that the clones become better than originals. The amount of work we give might improve them to perfect. That was only my imagination, but situation like this seems realistic to me.

To sum up I have to say that despite all the disadventages of cloning it is useful enough not to be banned.
