What is my personal opinion about stem cells therapy?

I think that it is a very bad idea because I would think that they are going to kill a baby. However, I would be very happy because when they take that embryo, I am going to be pretty healthy, but I could think of other opinions because maybe I can be like that baby, and I don't want that scientists use me to kill me. By the way, I could have some diseases like Parkinson's disease, Alzheimer's disease, Heart disease, Stroke, and some other diseases. If I have Parkinson's disease, and if I have to take a stem cell therapy, I would decide, and my decision is not to do it because instead of killing a baby they can find different options to get stem cells.
