What I really want to know is if humans have the right to kill a person to further research to save another. Personally, I don't believe that is right. Stem-cell research needs embryos that will become human beings to further its progression. Would it not make just as much sense to just let those embryos become people with the hope that they themselves could become great doctors and find cures? Stem-cell research may or may not prove its worth, but even if it does, it will come at a cost.
