"The Island" - The Movie's Burning Question

The question of my weekend:

If you paid 5 million dollars for a labortory cloned/genetic mass/body parts of yourself that can be used in order to cure your own future ills, and then realized that the company selling you this cloned/genetic mass/body parts of yourself was actually producing a cloned genetic human (your twin) and keeping them alive until you needed the body part/s, once realizing this, would you still order your cloned replica killed in order to save yourself?

Hmmm! I think I actually did well trying to get the question out considering the dynamics of the heated discussion I've just had with some close friends who had shocking answers to the question.

Let's see if this can become clearer. What if your clone (a living, breathing person) shows up at your door, someone that looks like you, someone that is thinking and has feelings shows up with a lot of questions. They have questions because they have been living in a world where they didn't know that you existed, they live in a world where they believe that their world far in the desert is the only life on the planet. This has been told to them by the medical/pharmaceutical company that basically gave birth to them in a laboratory so that you may live longer by using their cloned body parts when needed.

Or - if the time comes that you need some transplant or you may be dying from some illness, you make a phone call. This phone call results in your clone believing that they've just won "the lottery" to be taken to this paradise island, when really - they are taken off to the land of death, used for their body parts in order to keep you alive.

Finding this out, would you still allow this to happen in order to keep yourself alive?
