Is it correct to say this?
A follower of natural moral law would allow the use of embryos for medical research (such as finding cures for diseases by using stem cells) because it reinforces the primary precept of "preserving life". Even though a follower of this ethical system may believe that an embryo is a human life, the doctrine of double effect means that it is allowed to use embryos in stem cell research. There is a negative side effect as the embryo doesnt become a person but the intention is to save many the life of a person who is suffering from a disease and hence, life is preserved.
Is this true? Or would the doctrine of double effect not allow for embryo/stem cell research?
