So back to stem cells, the arguments in >>14,15 then boil down to the point that stem cells are alive but not individual. They are harvested from portions of a human body which are alive but not individual. And since they come from a human which is an individual, the only person responsible for their disposal is the person from whence they came. Given that person's consent, the scientists may do what they like. Also, murder involves the killing of an individual, not a living thing. Cutting off someone's arm isn't murder, nor is the cutting out of an embryo.

Note that there's no GOD in any of this. It's argued from non-religious philosophy and science.
